Terry and Ed start a lawn mowing business and purchase the mowers and equipment for $1,300. They charge $15 for each lawn and use $2 worth of gas for each job. How many lawns must Terry and Ed mow before breaking even?

Solution

Let the number of lawns they mow be x\'

So, Total charges for mowing x lawns = 15*x

Cost og gas used = 2x

Total investment for mowing = $ 1300 +2x

So, breakeven : Total charges for mowing x lawns = Total investment for mowing

15x = 1300 +2x

15x -2x = 1300 +2x -2x

13x = 1300

x = 100 lawns
