A school 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 yearbook 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 in the form R(x)=(500+ax)(50-bx). Find the values of a and b.

we have to calculate the values of A and B, so we have to:

Since the equation is:

And the following information was 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.

So knowing that by increasing 100 more books sold this is equal to A and the decrease in value is going to be equal to b.
