Eli wants to combine 0. 5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. How much of the 35% acid solution should Eli add? gallon.

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
