Sara can take no more than 22 pounds of luggage on a trip. Her suitcase weighs 112 ounces. How many more pounds can she pack without going over the limit?
Convert 112 ounces to pounds.
1 ounce = 0.0625 pounds
112 * 0.0625 = 7
So 112 ounces is equal to 7 pounds, now subtract this from the limit:
22 - 7 = 15
So she can pack 15 more pounds without going over the limit.
