    First you make sure you have all your variables using same measurement - cents (since it is the smallest)

    $100 = 100*100 cents = 100,000 cents

    1 quarter = 25 cents

    1 nickel = 5 cent

    1 dime = 10 cents

    the test of your problem said that:

    you have $100 in i don't know how many coins of quarters, nickels and dimes

    100,000 = X * (25+5+10)

    we have to find X:

    100,000 = X * (25+5+10)

    100,000 = X * 40

    X = 100,000/40

    X = 2,500 coins
