    for number 1 is it that she had 13candles to start with?

  • Math word problem -

    so 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

  • Math word problem -

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