Thread: Minimum Number of Lawns

Thelma and Laura start a lawn-mowing business and buy a lawnmower for $225. They plan to charge $15 to mow one lawn. What is the

minimum number of lawns they need to mow if they wish to earn a profit of at least $750?

First need to regain invest ,so must earn $225 first,then it will be profit.
so (225+775)/15 ,that is minimum number of lawns they need to mow if they wish to earn a profit of at least $750
