1. The population of a city is 85,000 and is growing at a rate of 3% each year. Find how many people live in this city after 13 years.​

85000 x 0.03 = 2550 (per year)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

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
