An Office Copier Has An Initial Price Of 2500
Regarding the calculation, just write the answer so that I can compare it with my own. 3
Advanced SD office copiers start at $ 3,200, service contracts cost پہلے 280 the first year, and add up to $ 100 a year. It is possible that the total cost of copier in X years is given by C (x) = 3200 + 230x + 50x
Average cost per year = C / x
Average C = 3200 / x + 230 + 50x
Meaning C = 3200 / x 2 + 50
0 = 3200 / x 2 + 50
50x 2 = 3200
x 2 = 3200/50 = 64
x = square (64) = 8
Eight years
