r+1 is less than or equal to 0.
What is r?
subtract one from each side of this equation:
there are 100 bushels of corn to be distributed out to 100 people.
the men get 3 bushels of corn each,
the woman get 2 bushels each,
and the children get 1/2 bushels each.
how can the bushels be distributed evenly among the people?
(so that the numbers add up to 100 people and 100 bushels)
Subtract one from each side, like bobpursley said.
