Sally and Peter have a lawn-mowing business. They earn $30 for
a large yard, $21 for a medium-sized yard, and $15 for a small
yard. If they mow 8 yards and there are at least 2 yards of each
size, what is the maximum amount of money they can earn?

The maximum amount of money Sally and Peter can earn is $126. This is because two of the yards will be large yards and would each earn them $30, for a total of $60, two medium-sized yards will earn them $21 each, for a total of $42, and two small yards will earn them $15 each, for a total of $30. Combined, this gives them a total of $126.
