Question

Suppose that a phone that originally sold for $800 and is worth 3/5 of its value each year after it is released. Write an equation for the value of the phone, y years after it is released.

Answer 1

800/(y*3/5)

Explanation:

Answer 2

v = 800 - 3/5y

Explanation:

v = value

y = years

The original cost/value was 800 dollars which means you would have to subtract the 3/5 decrease in value each year.

v = 800 - 3/5y
