    Answer:

    13 quarters, 26 nickels.

    Step-by-step explanation:

    n will be number of nickels, q will be number of quarters, and we have 39 total coins

    so n + q = 39 (number of nickels + number of quarters = 39 coins.

    The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)

    which means

    n + q = 39

    2q + q = 39

    3q = 39

    q = 13

    and she has 2 times as many nickels as quarters… 2 x 13 = 26 nickels

    LMK if you have questions.

    If you want to double check the money,

    n(0.05) + q(0.25) = 4.55 is the equation to use.

    26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55
