Question

Ian bought a used car. The value, y , of the car x years after his purchase is modeled by the equation y = 6500(0.875)x . What was the value of the car when Ian bought it?

Answer 1

6500

Explanation:

y = 6500(0.875)^x

When bought x = 0

y = 6500(0.875)^0

A number raise to 0 equals 1

y = 6500 * 1

y = 6500
