A bag of chips weighs 20 ounces, and a tin of cookies weighs 9 ounces. If Jasmine buys 6 bags of chips and 4 times as many tins of cookies, how many pounds does she have to carry? Let's answer step by step:
Jasmine’s bags of chips weigh 20 * 6 = 120 ounces. Jasmine buys 6 * 4 = 24 tins of cookies. Jasmine’s tins of cookies weigh 9 * 24 = 216 ounces. She has to carry 120 + 216 = 336 ounces. She has to carry 336 / 16 = 21 pounds. The answer: 21.
