**Reiny**, Tuesday, March 13, 2012 at 12:13amso 1/5 of the candles are left or 8 are left

so she must have had 40 candles

check: 4/5 of 40 = 32

so she has 8 left.

#2. let the number of quarters be x

then the number of dimes is 2x

and the number of nickels is 2x

25x + 10(2x) + 5(2x) = 165

55x = 165

x = 3

there are 3 quarters, 6 dimes and 6 nickels.

check: 3(25) + 6(10) + 6(5) = 165
