I presently have $10,000 in the bank. At the beginning of each of the next 20 years, I will invest $4,000, and I expect to earn 6% interest per year. After 20 years I pay $15,000 in closeout fees on on the investment. At the end of the investment and fees how much money will I have? (answer $108,900)

I was given the answer by my professor I just need to know how to complete this with Excel formulas.
