Find the solutions of the system: y = 2(5)-x and x y = 2 User: 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" could be used to determine when the two depreciation models will give the same value for the lawnmower.
Solution
1. y = 1,500(0.3)^x
2. y = 1,500 - 300x
1,500(0.3)^x = 1,500 - 300x
0.3^x = 1 - 0.2x
(0.3)^x = 1 - 0.2x
y = 1,500(0.3)^x and y = 1,500 - 300x
