Amy is in a craft store looking at packages of pom-poms. amy sees packages of four red pom-poms. amy says she can buy seven packages of four pom-poms or four packages of seven pom-poms because she will get the same total of pom-poms. is amy correct? show all mathematical thinking.

First, let's calculate the number of pom poms she get if she buys 7 packages of 4.
Multiply each number to get the value.
7 x 4 = 28
Shell get 28 pom poms.

Now let's calculate the number of pom pom if she gets 4 packages of 7.
4 x 7 = 28
She gets 28 pom poms.

Therefore, both of these options gets the same amount of pom poms, which is 28, therefore Amy is correct.
