Answer:
x + y = 745
23.50x + 58.75y = 29,668.75
Step-by-step explanation:
Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:
x + y = 745
Since the home edition costs $23.50, and the business edition costs $58.75:
The money earned from home edition is = 23.50x
The money earned from business edition is = 58.75y
Since the company earned $29,668.75:
23.50x + 58.75y = 29,668.75

A holiday costs £1200. Work out the price after a 7% discount.
Answer:
1116
Step-by-step explanation:
0.93(1200)
1116
Discounts are used to reduce the price of an item
The price after a 7% discount is £1116
How to determine the price after discountThe given parameters are:
Cost = £1200
Discount = 7%
So, the price after the discount is:
Price = Cost * (1- Discount)
This gives
Price = £1200 * (1- 7%)
Evaluate the product
Price = £1116
Hence, the price after a 7% discount is £1116

Jake paid $40.50 per solar panel for eight panels and an additional installation fee for a total of $338.50. Jen paid $42.99 per panel for eight panels and an additional installation fee for a total of $354.42. Find the difference between the installation fees Jake and Jen paid.
Answer: $4.00
Step-by-step explanation:
$40.50 * 8 = $324.00
$338.50 - $324.00 = $14.50
Jake’s installation fee is $14.50
$42.99 * 8 = $343.92
$354.42 - $343.92 = $10.50
Jen’s installation fee is $10.50
To find the difference between the two fees, you subtract the larger fee by the smaller fee.
$14.50 - $10.50 = $4.00

HELP ME!!! y is inversely proportional to square of x. Given that y=3 when x=7, find the value of x when y=18.375 TYSM!
Answer:
The value of x is -2√2 or 2√2.
Step-by-step explanation:
Given that y is inversely proportion to x², y ∝ 1/x². So the formula will be y = k/x² where k is the constant. In order, to find the value of k, you have to substitute the values of x and y into the formula :
[tex]y = \frac{k}{ {x}^{2} } [/tex]
[tex]let \: x = 7 \\ let \: y = 3[/tex]
[tex]3 = \frac{k}{ {7}^{2} } [/tex]
[tex]3 = \frac{k}{49} [/tex]
[tex]3 \times 49 = k[/tex]
[tex]k = 147[/tex]
[tex]y = \frac{147}{ {x}^{2} } [/tex]
Next, you have to substitute the y value into the equation to find x :
[tex]let \: y = 18.375[/tex]
[tex]18.375 = \frac{147}{ {x}^{2} } [/tex]
[tex]18.375 {x}^{2} = 147[/tex]
[tex] {x}^{2} = \frac{147}{18.375} [/tex]
[tex] {x}^{2} = 8[/tex]
[tex]x = ± \sqrt{8} [/tex]
[tex]x = - 2 \sqrt{2} \: \: or \: \: 2 \sqrt{2} [/tex]

Help please, which one is a quadratic expression?
Answer: -6x^2 + 3 and 1 - 4x^2
Step-by-step explanation:
A quadratic expression is an expression that can be in the form ax^2 + bx + c, where a, b, and c are all constants, and a does not equal 0. (ax must be squared, it can't be raised to a power other than 2)
-6x^2 + 3 and 1 - 4x^2 can be in the form ax^2 + bx + c. Therefore, they are the quadratic expressions.

Yummy Cookies just opened a brand new cookie bakery. The baker wants to increase the number of cookies he makes and sells each month. So far, the carrot cake cookie has been the best seller. In January, the baker made 14 of these cookies. In February, the baker doubled the January order, and took 5 cookies home to his family. The baker left the rest of the carrot cake cookies at the bakery to be sold. Every cookie left at the bakery sold. If this pattern continues, how many cookies will the baker sell in March and April?
Answer:
Number of cookies sold in March= 46
Number of cookies sold in April= 92
Step-by-step explanation:
Number of cookies made in Feb= 2×14= 28
Number of cookies sold in Feb= 28-5= 23
Number of cookies sold in March= 2× number of cookies sold in Feb
Number of cookies sold in March= 2× 23= 46
Number of cookies sold in April= 46×2= 92

Connor is stuck in a traffic jam on a single-lane road. The traffic report tells him the
traffic jam stretches for 5.5 miles.
If Connor assumes each car is about 12.5 feet long, which calculation is most
reasonable for Connor to use to find about how many cars are stuck in the traffic jam?
Answer:
Cornor should divide the total length of the road on which there is traffic by the length of each of the cars
Step-by-step explanation:
The best calculation he can use is to divide the total length of the road on which we have the traffic by the length of each of the cars
Mathematically, the best way to go about this is to convert the miles to feet then divide by the length of each of the cars
Mathematically 1 mile = 5280 feet
so 5.5 miles will be = 5280 * 5.5 = 29,040 feet
It is this length we shall now divide by 12.5 ft
And that is 29,040/12.5 = 2,323.2
Which is approximately 2,323 cars
Dr. Santiago is contemplating the impact of an antibiotic on a particular patient. The patient
will take 840 milligrams, and every hour his body will break down 45% of it. How much will
be left after 5 hours?
If necessary, round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
If his body is breaking down 45% of the medicine, it is losing 100% - 45% = 55%. This means that while he is LOSING 45% of the medicine, he is KEEPING 55% of it. This is an exponential function of the type
[tex]y=a(b)^x[/tex] where y is the amount of medicine after the increase or decrease (b) of the original amount, a. The number of hours is represented by x.
Our original amount is 840 mg, so a = 840. And if we are losing .45, we are retaining .55, so b = .55. The model for this situation is
[tex]y=840(.55)^x[/tex]
If we want to find out how much medicine is left after 5 hours, we sub in a 5 for x and solve for y:
[tex]y=840(.55)^5[/tex] and
y = 840(.0503284375) so
y = 42.2758875 or, rounded to the nearest tenth,
y = 42.3 mg
41/17 rounded to the nearest hendreth

A saleperson receives a base salary of $37,000 in commission of 8% of the total sales of the year if the sales person sells $265,000 of merchandise what is his total salary for the year
Answer:
Sale-person's total salary for the year is $ 82,050
Step-by-step explanation:
Base salary of salesperson = $37,000
commission percentage of salesperson = 17% of sales
sales made in a year = $265,000
commission for salesperson in $ = 17% of sales
commission for salesperson in $ = 17 / 100 * $265,000 = $45,050
Thus, total commission for the given year salesperson is $45,050
Total salary for year = Base salary + total commission for the given year
Total salary for year = $37,000 + $45,050 = $ 82,050 (Answer)

A line which intersects one of two parallel lines intersects the other also.
A. Always
B. Sometimes
C. Never
(I put always, but that turned out to be incorrect)
Answer:
Sometimes
Step-by-step explanation:
When a line intersects one of two parallel lines, it will sometimes intersect the other also.
Ex. If one of the parallel lines was at y=2, the intersecting line could be y=2.
The correct answer is- B. sometimes
A line which intersects one line need not necessarily intersect other line also , also the two parallel lines never intersect.
What is transversal?
A transversal is a line that passes through two lines in the same plane at two distinct points. Its a line that crosses other lines.
here, in the question its not mentioned about transversal so its not necessary that line which intersects one parallel line also intersect other. Hence, its sometimes either or situation that depends upon the probability of the situation that a line will intersect or not.
hence, the correct answer is- B. Sometimes.
