Aschool typically sells 500 yearbooks each year for $50 each.
the economics class does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook.
let x represent the number of $5 decreases in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). find the values of a and b.

a=100 and b=5

Step-by-step explanation:

Given: A school typically sells 500 yearbooks each year for $50 each.

The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.

Let x represents the number of $5 decreases in price.

Then the new price (in dollars)=50-5x

Total yearbook sold=500+100x

If the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook.

Then the revenue function will be

On comparing this with the given revenue expression we get

a=100 and b=5.
