The value of a new car purchased for $24,900 decreases by 10% per year. Which exponential decay model represents this situation?

a. y=24,000 x (0.9) ^x
b . y=24,000 x (0.1)^x
c. y=24,000 ^x
d. y=90.1)^x

2. How much will the car be worth after 5 years?

Respuesta :

it will be A bc youre multiplying the total amount of the car by how much it is worth. If it is decreasing by 10% each year then it is worth 90% of its value, hence 0.9
Since it decreases by 10% we have to write 0.9. The correct answer is A because it is the only one with the principal of 24,000 and has a 0.9 decrease.

Part2:
you put 5 where the x is and you get 
$14,171.76
