Aschool typically sells 500 yearbooks in a year for $50 each. the economics class does a project and discovers that they can sell 125 more yearbooks for every $5 decrease in price. the revenue for year book sales is r(x)+(500+125x)(50-5x). to maximize profit, what prices should the school charge for the yearbooks?

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
