    Answer:

    THere are 33 quarters and 151 nickles

    Step-by-step explanation:

    Let q be the number of quarters in the bag

    Let n be the number of nickles in the bag

    Because there are a total of 184 we have a equation:

    q + n = 184

    Because the total value of the coins is $15.80 so we have another equation

    0.25q + 0.05n = $15.80

    <=> q + 0.2n = 63.2

    We have q + n – (q + 0.2n) = 184 – 63.2

    <=> 0.8n = 120.8

    <=> n = 151

    <=> q = 184 – 151 = 33
