Question 72706: Troy does yard work earning $25 for mowing lawns and $40 the "works", if he earned $370. How many yards did he mow and how many got the "works"? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! To make it easier, first notice that the number of lawns mowed has to be even.
If it were odd, The total money earned would have to end in "5"
Make a chart with m = # lawns mowed and w = # of "works" done
m..w
2..8
4..x
6..x
8..x
10..3
12..x
14..x
Try the combinations yourself. The only ones that can possibly
give you $370 is m=2,w=8
and m=10,w=3
