Jill has $3.50 in nickels and dimes. If she has 50 coins, how
many of each type of coin does she have?
--------
Let number of nickels be "x"; Value of these is 5x cents
Number 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 (number of nickels)
50-x=20 (number of dimes)
------------
