Question: Kekai is running a sundae booth at the carnival. On Monday, he makes a total of 40 sundaes, and he puts 6 m&ms on each sundae. On Tuesday, he makes a total of 20 sundaes, and he puts 10 m&ms on each sundae. If each m&m pack contains 40 m&ms, how many m&m packs does Kekai use?
Answer with step-by-step thinking:
On Monday, Kekai uses 40 * 6 = 240 m&ms. On Tuesday, Kekai uses 20 * 10 = 200 m&ms. Kekai uses a total of 240 + 200 = 440 m&ms. Kekai uses a 440 / 40 = 11 m&m packs.
So the answer is 11.
