Temperature (x) Kilowatts (y) 73 680 78 760 85 910 98 1510 93 1170 83 888 92 923 81 837 76 600 105 1800 Approximately what percentage of the variation in Kilowatts is accounted for by Temperature in this model

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?
