Carla’s vet suggested that her new puppy have at least 64 square feet of exercise space. Carla plans to build an enclosed, square exercise pen in her back yard. How much fencing will she need for this exercise pen?

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
