Jason has already used 12.3 cans of paint painting furniture. he is painting
chairs that use 6 cans of paint.
let the total cans of paint used be represented by p.
let the number of chairs painted be represented by c.
an equation that represents this scenario is:
p = 6c + 12.3
what is the total number of cans used if he paints 8 chairs?
answer as a decimal.

Aschool typically sells 500 yearbooks each year for 50 dollars each. the economic calls 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 decrease in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). to maximize profit, what price should the school charge for the yearbooks? what is the possible maximum revenue? if the school attains the maximum revenue, how many yearbooks will they sell?
