Answer: 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

It is going to be minus, so negative because a positive times by a negative always gives you negative.
i there would be two negative and three positive factors it would be a minus times by a minus which gives you a plus. if the amount of negatives is odd it will be negative, if it is even then it is going to end up being a positive.
hope i could help.:)
