Question

Austin buys 30 cups he places 4 balls in each cup how many cups does he need

Answer 1

Umm do you mean how many balls he needs? If that’s what you ment all you have to do is 4 x 30 and 4 x 30 equals 120.

Answer 2

I think you misworded this question. If he buys 30 cups and puts four balls in each, then he would still have 30 cups.
