Question 787772: Jordan has a jar of quarters. When he has 60 quarters in the jar, the jar weighs 52 ounces. When there are 125 quarters in the jar, the jar weighs 65 ounces. What is the weight of the empty jar? Answer by solver91311(24713) (Show Source):
60 times the weight of each quarter plus the weight of the jar is 52 ounces. 125 times the weight of each quarter plus the weight of the jar is 65 ounces. Put those two statements together and you get 65 times the weight of a quarter is 13 ounces, so a quarter weighs about 0.2 ounces. And you can take it from there I would guess.
