John has $2.50 in nickels and dimes in his wallet. He has twice as many dimes as nickels. How many of each coin does he have? Let dimes = _____. Let nickels = _______. Equation:________________

  • math - ,

    If dimes = D and nickels equals N, and we let D = 2N,

    Then 5 N + 10 D = 25 N = 250

  • math - ,

    Dimes=d Nickels=n

    .05n + 0.1d = 2.50
    d = 2n
    0.05n + 0.1(2n) = 2.50
    0.05n + 0.2n = 2.50
    0.25n = 2.50
    n = 2.50/0.25
    n=10
    d=20
    There are 10 nickels and 20 dimes.
