Question

1. A car costs $10,520 and decreases in value by 15% every year. How much will the car be worth after 4 years?​

Answer 1

5491.50575

Explanation:

10520 x (1 - 0.15)^4
so first you subtract 1 from 0.15 and that equals 0.85 then you times 0.85 itself cuz it decreases value for a total of four years and that would make 0.85^4 =0.52200625 now you 10520 x 0.52200625= 5491.50575
ps. depending if your adding or subtracting percents it will either 1+ or 1- then whatever percent into decimal hope this helps!
