Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day. According to a

Degger [83]

Answer:

The equation that models this scenario $b(x)=(3+0.5x)(38-4x)$

Step-by-step explanation:

First we convert 50 cent into dollar,

1 cent = $\frac{1}{100}$ dollar

1 cent = 0.01 dollar

50 cent = 0.5 dollar

According to question,

x is the number of 50¢=$0.5 price increases.

b(x) is the revenue generated

He currently charges $3 per book.

i.e. price of book = 3+0.5x

Quantity or average = 38 per day

According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.

i.e. quantity became 38-4x

Revenue = Price × Quantity

The required equation is given by,

$b(x)=(3+0.5x)(38-4x)$

Johanna took $125 to the mall. She bought 5 shirts (s) that cost the same price. Which expression represents the amount of money

I think its something like: Money Leftover = 125 - (price of one shirt * 5)

Step-by-step explanation:

just use variables in the place of "price of one shirt" and "Money Leftover".

multiplying the price of one shirt by five since she buys 5 of the same shirt and subtracting that value from her budget will leave you with the amount of money she had left after the purchase.

What is the slope of the line through (- 1, - 7) and (3, 9) ?

Fynjy0 [20]

Answer:

C. 4

Step-by-step explanation:

Use the slope formula:

$m=\frac{y2}{x2} -\frac{y1}{x1}$

m = the slope.

Substitute the values into the formula:

$\frac{9}{3} -\frac{-7}{-1} =\frac{?}{?}$

Solve:

$\frac{9}{3} -\frac{-7}{-1} =\frac{16}{4}$

Simplify 16/4:

$\frac{16/4}{4/4} =\frac{4}{1}=4$
