The value of a graphing calculator is $225. After 2 years, the value of this calculator is $160. Find the value of the calculato
OlgaM077 [116]
To find the value of the calculator after 5 years, you need to find how much the price of the calculator drops each year. From years 0 to 2, it seems that the price of the calculator has dropped by some amount of money x. To find how much the calculator drops each year, first you will need to subtract 160 from 225 (225-160) to get 65. Next, you need to divide 65 by 2 (65/2) to get $32.50.

I believe that in order to find the price after 5 years, you will need to multiply 32.5 by 5 (32.5*5) to get $162.50. Next you would subtract $162.50 from $225 (225.00-162.50) to get $62.50.

So, the price of the calculator after 5 years is $62.50!

I hope this helps!
