Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! John has $9.95 made up of nickles and dimes. The number of nickels is one more than 2 1/2 times the number of dimes. How many of each does he have?
---------------
Let number of dimes be "x" ; value of these is 10x cents
Number of nickels is (5/2)x+1 ; value of these is 5[(5/2)x+1]= (25/2)x+5 cents
-------------------
EQUATION:
value + value = 995 cents
10x + (25/2)x + 5 = 995
22.5x = 990
x = 44 ( number of dimes)
(5/2)x+1 = 111 ( number of nickels)
==============
