My question is: Nora is selling muffins to raise $120 for an upcoming school trip. She has packaged the muffins in cases. Each case has three packs of muffins. Each pack has four muffins. If she prices each muffin at two dollars, how many cases of muffins must she sell to raise enough money for the trip? Your thoughts:

If Nora prices each muffin at two dollars, she will sell 1 pack for 2 * 4 = 8 dollars. Since there are 3 packs to a case, the case will be sold for 3 * 8 = 24 dollars. It therefore means that she needs to sell 120 / 24 = 5 cases of muffins. The final answer: 5.
