From 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected to decline at a rate of 2.8% each following year. how many cars will be sold in 2020

To determine the number of cars that will be sold by the year 2020, we will use the equation,

N = (N1) (1 - r) ^ (t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

N = (500) (1 - 0.028) ^ (8)

N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.
