Question 909772: Joey has 60 coins in his piggy bank. All the coins are nickels and quarters.The total value is $11.60. How many quarters are in the piggy bank? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! If all 60 coins were quarters, Joey would have 60 * .25, or $15.00
His actual total is $11.60, a difference of $3.40
The difference between a quarter and a nickel is .20
3.40/.20 = 17
He has 17 nickels @ .05 = .85
That leaves 43 quarters @ .25 = 10.75
.85 + 10.75 = $11.60
