This math problem has got me stumped: 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?
Can you show me the way?
