We could represent this as an equation:
47x = $209, where x is the number of lawns mowed.
What we could do is divide 209 by 47 to find out how many lawns Jerry would need to mow. This would give us about 4.4 (when rounded). Since Jerry has to mow entire lawns, we would have to round that up to 5 lawns. Jerry would earn $235 for those, which is more than enough for those new video games.
