A business purchases a copier for $5,500 and anticipates it will be worth $2,500 after 10 years. Use straight-line depreciation to find a linear model for the depreciated value V of the copy machine after t years of use.

A. V = -5,500 + 300t

B. V = 300 - 5500t

C. V = -300 + 5500t

D. V = 5,500 - 300t

#2 Since the value starts at $5500, you know the solution will have "5500-..." in it. That leaves only (D)

See whether you can justify the rest of the solution.

**Kelsi**, Saturday, October 12, 2013 at 11:13amA for the 1st one, 45 dollars per hour, x, is 45x. The fixed-service is a one-time thing so it's c = 45x + 65.The 2nd one is D. The original cost of the copier is 5,500. 5500-2500 = 3000. This is the cost reduction over the ten years. 3000/10 is 300: The amount it gets reduced by every year. For D, when you plug in 10, you get 2,500.
