Melissa and Steve bought new cars. The value of Melissa’s car can be calculated using the function f(x) = 16,000(0.9)x, where x is the number of years after the car was purchased. The value of Steve’s car can be calculated using the function f(x) = 18,000 – 1,500x, where x is the number of years after the car was purchased. After 7 years from the purchase of their cars, this statement is true.
