She makes a profit of £542.40. How many Amazebars did she sell?
Answers
Answer:
Nina sold 24 Amazebars Plz Mark Brainliest
Step-by-step explanation:
Cost:
80 x 0.40 = 32
180x 0.30 = 54
40 x 0 = 0
Total = 86
Income
80 x 2.25 = 180
180 x 2.25 = 405
X x 2.25 = 2.25x
Total = 585 + 2.25x
How many did she sell:
553 = 585 - 86 + 2.25x
553 = 499 + 2.25x
553 - 499 = 2.25x
54 = 2.25x
54/2.25 = x
24 = x

Two sporting goods stores are having discount sales on basketballs. At one store, a basketball is on sale for 20% off the regular price of $24.95. the other store, the same kind of basketball is on sale for 25% off the regular price of 25.80 . What is the difference between the sale prices of the two stores?
Answers
Answer: $0.61
Step-by-step explanation:
1. Find the retail price of each store by multiplying the normal price by% discount to get a discount - and then opt out.
store A: 24.95 * 20% (or 0.20) = 4.99 (discount)
24.95 - 4.99 = 19.96 (sale price)
store B: 25.80 * 25% (or 0.25) = 6.45 (discount)
25.80 - 6.45 = 19.35
To find the sale price difference, subtract 19.96 - 19.35 = 0.61

24 : 3 = 8
24 : 4 = 6
24 : 6 = 4 and so on.

What is the expanded form of the expression ∑i=04i4? 04+14+24+34 14+24+34+44 02+42 04+14+24+34+44
Answers
The expression is an illustration of the summation notation
The expanded form of the summation notation [tex]\sum\limits^{4}_{i = 0} i^4[/tex] is 0^4 + 1^4 + 2^4 + 3^4+4^4
How to determine the expanded formThe summation notation is given as:
[tex]\sum\limits^{4}_{i = 0} i^4[/tex]
The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4
So, we have:
[tex]\sum\limits^{4}_{i = 0} i^4 = 0^4 + 1^4 + 2^4 + 3^4+4^4[/tex]
Hence, the expanded form of [tex]\sum\limits^{4}_{i = 0} i^4[/tex] is 0^4 + 1^4 + 2^4 + 3^4+4^4

Answers
Answer:
y = 2/3x + 5
Step-by-step explanation:
y = mx + b is slope intercept form
You have the equation in order but in order to complete it, you need to remove the 3 in front of the y.
#1: 3y = 2x + 15 (Remove the 3 by diving all the numbers on the opposite side)
Final Answer: y = 2/3x + 5
Answer: y=2/3x-5
Step-by-step explanation:
Rearrange 2x−3y=15 into this form
subtract 2x from both sides.
divide ALL terms on both sides by - 3
