You can put this solution on YOUR website! Jill has $3.50 in nickels and dimes. If she has 50 coins, how many of each type of coins does she have?
---------------
Let number of nickels be "x" ; value of these is 5x cents
# of dimes is "50-x" ; value of these is 10(50-x)= 500-10x cents
------------------
EQUATION:
value + value = 350 cents
5x + 500-10x = 350
-5x = -150
x = 30 ( # of nickels)
50-x=20( # of dimes)
