    Nickel is x

    quarter is y

    x + y = 50 coins

    5x + 25y = 530 cents

    if x = 49

    5 * 49 = 245 + 25 = 270

    if x = 45

    5 * 45 = 225 + (25 * 5) = 350

    if x = 40

    5 * 40 = 200 + (25 * 10) = 450

    if x = 36

    5 * 36 = 180 + (25 * 14) = 530

    There will be 36 nickels and 14 quarters.
