Question 904707: Madeline has 60 coins some are quarters the rest are half dollars total value of coins is $19.50 how many of each denominations does she have? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! h+q=60,
50*h+25*q=1950
h=60-q
50*(60-q)+25*q=1950
3000-50q+25*q=1950
-25*q=-1050
q=42
h=60-q
h=18 at $.50 and q=42 at $.25
check
18+42=60
50*h+25*q=1950
50*18+25*42=1950
900+1050=1950
1950=1950
ok
