Question

The value of a graphing calculator is $225. After 2 years, the value of this calculator is $160. Find the value of the calculator after 5 years.

Answer 1

225-160=65
65/2=32.5
Following this pattern, we do 32.5•5, and then subtract that from 225.
32.5•5= 162.5
225-162.5= 62.5.
My best guess is that the calculator is worth 62.5 dollars in five years.
