Lisa needs to make 2 times as many tunas as cheese sandwiches and 4 times as many ham as cheese sandwiches. If Lisa makes 56 sandwiches, how many of each of the 3 kinds will she make?

Let c represent the cheese sandwiches.
c + 2c + 4c = 56
7c = 56
c = 8
Lisa makes 8 cheese sandwiches.
I'm sure you can figure out how many tuna and ham sandwiches she made.
