Which expression fits this description? • The expression is the sum of two terms.
• The first term is the product of 2 and a.
• The second term is the quotient of b and 4.

A. 2a + (b-4)
B. (2+ a) + b/4
D. 2a + b/4
C. (2+a) + (b-4)

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
