Answer:
Fred has 7 violet balloons and Mary has 21 violet balloons.
Step-by-step explanation:
Okay so first things first I notice that in the problem it states that Mary has 3 times as many balloons as Fred and Fred has 7 balloons. First you will multiply 7*3 because that's the amount of violet balloons Fred has (7) and Violet has 3 more. Then after you multiply 7*3 you will get 21, so Mary has 21 balloons.
