Hi Kyla,

Since the number of butterflies that Jenny has depends on the number that Charles and the number that Charles has depends on the number that Chase has if I just knew how many Chase has I would be done. Thus, to set up an algebraic expression I am going to let the number of butterflies that Chase has be the unknown.

Let $B$ be the number of butterflies that Chase has. In terms of $B$ how many butterflies does Charles have? Jenny has 7 times this number so how many butterflies does Jenny have? The sum of these three numbers is 560 so solve for $B.$

When I do this I don't get an integer for $B.$ Are you sure you have typed the problem correctly?
