A car worth $43,000 brand new, depreciates at a rate of $2000 per year. What is the formula that describes the relationship between the value of the car (C) and the time after it has been purchased (t)?
Let t be the number of years since purchase. Depreciation means the value decreases, so we have:
C = 43000 - 2000t
Let t be the number of years since purchase. Depreciation means the value decreases, so we have:
C = 43000 - 2000t
