(15. higher order thinking the length of a rectangle is twice
the width. the area of the rectangle is 90 square units. note
that you can divide the rectangle into two squares.
a. which irrational number represents the length of each
side of the squares?
b. estimate the length and width of the rectangle.

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
