Given an exponential function for compounding interest, a(x) = p(.82)^x, what is the rate of change?
a. –18%
b. –8%
c. 0.82%
d. 82%

A is the correct answer.

Step-by-step explanation:

.82=1+r --> .82-1=1-1+r --> -0.18=r --> -18%

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
