**Reiny**, Sunday, February 26, 2012 at 9:02pmnumber of quarters --- x

number of dimes ----- 2x

number of nickels ----- 130 - x - 2x = 130-3x

5(130-3x) + 10(2x) + 25x = 950

650 - 15x + 20x + 25x = 950

30x = 300

x = 10

So there were 100 nickels

Check:

so 10 quarters --> $2.50

20 dimes and ---> $2.00

100 nickels -----> $5.00 -->total = $9.50
