Question
Nick budgets from 300 pesos to 900 pesos for trees and/or bushes to landscape his yard. After shopping around, he finds that good trees cost 150 pesos and mature bushes cost 75 pesos. What combination of trees and/or bushes can he afford to buy?

Note that each tree costs the same as 2 bushes.
Nick can buy 2-6 trees and 0 bushes, or
4-12 bushes and 0 trees.
Each tree can be replaced by two bushes, so it's fairly easy to see how to keep within budget by replacing each tree by 2 bushes.
