Amy has a collection of marbles in three sizes, small, medium, and large. She has five times as many small marbles as medium marbles. The number of large marbles is two more than three times the number of medium marbles.

If Amy has a total of 560 marbles, how many of each size does she have? Show your work.

m

s = 5 m

l = 2 + 3m      this is all given.....they should sum to 560

 

m +     5m     +     2 + 3m   = 560      solve for m, the number of medium....then   s = 5m  and  l = 2 + 3m
