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

complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50¢ price increases.

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

Step-by-step explanation:

Let

b= revenue generated  per day

x=  is the number of $0.5 price increases.

b = price x quantity (1)

Let derive the price function for the model

price = $3 per book

However, assuming x number of price increase by $0.5, future price is given as :

price = (3+0.5x) (2)

quantity = 38 per day

For every x number of price  $ 0.5 price jump, quantity reduces by 4. So the quantity at any given time is given by:

quantity = (38-4x)(3)

Substituting into equation (1),

We have:

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