A landscaper buys a new commercial-grade lawn mower that costs $2,800. Based on past experience, he expects it to last about 8 years, and then he can sell it for scrap metal with a salvage value of about $240. Assuming the value of the lawn mower depreciates at a constant rate, which equation could be used to find its approximate value after x years, given that x < 8?
A. y = -8x + 2,560
B. y = -240x + 2,800
C. y = -320x + 2,800
D. y = 240x - 2,560
Answer:C
