Please show all your work step by step all the formula that is used and avoid write them down and take pictures. I rather want it done in computer, so that i can read it.

Hand writing is hard to read sometimes.

A. How much will you have saved after 6 years by contributing $1200 at eh end of each year if you expected to earn 11% on the investment?

B. A business owner plans to deposit his annual profits in an investment account earing a 9% annual return. If the owner starts with their first deposit today for $22000. And expects to make the same profit for the next 7 years, how much will be saved for retirement at the point?

C. An investor plans to $500 a year and expects to get a 10.5% returns. If the investor makes these contributions at the end of the next 20 years, what is the present values of this investment today?
