Jeramie has a jar of nickels and dimes. There are 200 coins worth $14.00. How many of each type of coin are in the jar. :)

  • Math -

    X Nickels.
    (200-X) Dimes.

    5x + 10(200-X) = 1400 Cents.
    5x + 2000 - 10x = 1400
    -5x = 1400 - 2000 = -600
    X = 120 Nickels.
    200-x = 200-120 = 80 Dimes.
