Large crates and small crates

-

A large crate holds twelve cartons of milk whereas a small crate holds only four cartons. I have five large crates and twenty small crates available. What is the smallest number of crates in total that I could use to store 110 cartons of milk?

    To use the smallest amount of crates, we need the most large crates we can get. If we trial and error the numbers nothing will come so we can do 5 large crates and 13 small ones which would in total be able to fit 112 cartons of milk but will only hold 110
