The value of a car decreases about 7% percent each year after it is manufactured. the 2017 honda civic costs $19,540

a) , where 'A' is the value of car after 't' years.

b) $12446.784

Step-by-step explanation:

Given: A new car that sells for $21,000 depreciates (decreases in value) 16% each year.

Then a function that models the value of the car will be

, where 'P' is the selling price of car, 'r' is the rate of depreciation in decimal, 't' is the time in years and 'A' is the value of car after 't' years.

Thus after substituting given value, the function becomes

To find the value after 3 years, substitute t=3 in the above function.

Hence the value of car after 3 years=$12446.784
