    For the average over 7 years to be 50,000 the total would be

    t = 7 * 50000

    t = 350000

    -------------------

    Amount earned over 4 years at 25000

    a = 4 * 25000

    a = 100000

    -------------------

    earnings needed over three years

    e = 350000 - 100000

    e = 250000

    needed average annual income

    n = 250000/3

    n ≈ 83,333

    $83,333 <––––
