You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night, you made a total of $104.50. You sold a total of 113 hot dogs and sodas combined. You must report the number of hot dogs sold and the number of sodas sold. How many hot dogs were sold and how many sodas were sold?

Answers

Answer:

35 hotdogs and 52 sodas sold.

Step-by-step explanation:

x = the number of hotdogs sold, x>0

y = the number of sodas sold, y>0

At the end of the night you made a total of $78.50:

1.50x + 0.50y = 78.50

You sold a total of 87 hotdogs and sodas combined:

x + y = 87

We have the following system of equations:

1.50x + 0.50y = 78.50

x + y = 87

What is a mathematical expression?

A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations. Mathematicians can multiply, divide, add, or subtract. An expression is structured as follows: Number/variable, mathematical operator, and expression.

It is given that the expression is, 9.3x = x +4

The value of x is obtained to make the expressions equal.

Apply the arithmetic operation in order to find the value of x.

9.3x = x +4

9.3x-x=4

8.3x=4

x=4/8.3

x=0.48

Thus, the expression below is equivalent since the value of x will be 0.48.

Joyce paid $94.50 for an item at the store that was 55 percent off the original price. What was the original price?

Answers

Answer:

$210

Step-by-step explanation:

The original price of the item = 100%

If the item was reduced by 55%, then the discounted price of the item = 100% - 55% = 45%

Therefore, $94.50 = 45% of the original price.

45% = 45/100 as a ratio

Using ratios, and letting [tex]x[/tex] be the original price:

                                                   94.50/[tex]x[/tex] = 45/100

Cross multiply:                    94.50 x 100 = 45 x [tex]x[/tex]

                                                       9450 = 45[tex]x[/tex]

Divide both sides by 45:                   210 = [tex]x[/tex]

Therefore, the original price of the item was $210

Alternatively, divide 94.50 by 45 to get the cost per 1%.  Then multiply this by 100 to get the original price (100%):

(94.50 ÷ 45) x 100 = 210

12. A Ford Taurus at Enterprise Rent-a-Car rents for $43.46 per day. You receive 150 free miles per day but are charged $0.25 per mile for any additional miles. How many miles can you drive per day, on average, and not exceed your daily budget of $60.00?

Answers

Price left for extra miles=60-43.46=16.54$

No of extra miles:-

[tex]\\ \tt\hookrightarrow 16.54/0.25=66.16mi[/tex]

Now

Total average miles

[tex]\\ \tt\hookrightarrow 159+66.16=216.16mi/day[/tex]

The number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be 216.16 miles.

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A Ford Taurus at Enterprise Rent-a-Car rents for $43.46 per day. You receive 150 free miles per day but are charged $0.25 per mile for any additional miles.

Let x be the number of miles that you drive and y be the total rent. Then the equation will be

y = 0.25(x - 150) + 43.46

Then the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be

60 = 0.25(x - 150) + 43.46

60 = 0.25(x - 150) + 43.46

16.54 = 0.25(x - 150)

66.15 = x - 150

x = 150 + 66.15

x = 216.16 miles

Thus, the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be 216.16 miles.
