**Reiny**, Thursday, October 28, 2010 at 4:55pmYour last four money questions are the same type

If will do one, then you try the others.

let the number of nickels be x

then the number of quarters is 16-x

5x + 25(16-x) = 220

5x + 400 - 25x = 220

-20x = -180

x = 9

so 9 nickels and 7 quarters

check: 9 nickels and 7 quarters = 16 coins

value: 9x5 = 7x25 = 220
