<PRE><B>Question 1106882</B>
the piggy bank weighs 850 grams when it is empty and weighs 7822 grams when it is filled with quarters.


that means the total weight of the quarters is 7822 - 850 = 6972 grams.


since each quarter weighs 5.6 grams, then the number of quarters has to be 6972 / 5.6 = 1245.


there are 1245 quarters in the piggy bank.


since there are 4 quarters to a dollar, then 1245 quarters / 4 = 311.25 dollars, or 311 dollars and 25 cents.
