Question

Mariah has fifteen dollars to spend at the food store. She buy 4 packs of cookies for $3 each. How much money did Mariah have left?

Answer 1

4 * 3 = 12 dollars that Mariah spent.

15 - 12 = 3 dollars that Mariah has left.

Hope this helps.

Answer 2

Three dollars. Because three dollars for each pack and there are four packs, is twelve. Fifteen (the money she has to spend on food) minus twelve (the money she spent) is three.
