Question

Ron buys a lawnmower for $1,500. The salesperson says the value will depreciate about 30% per year over the next few years. However, his neighbor says it is likely to depreciate about $300 per year.

Which system could be used to determine when the two depreciation models will give the same value for the lawnmower?

y = 1,500(0.3)x and y = 1,500 - 300x
y = 1,500(0.7)x and y = 300 - 1,500x
y = 1,500(0.7)x and y = 1,500 - 300x
y = 1,500(0.3)x and y = x - 300
