Please if you can provide the formulas but also briefly explain it so I understand. (Also not too sure if I did number 12 correctly, please let me know if it's not correct).

I can't seem to uplad the excel file or I would.

12	In the Loan sheet, insert formulas in the range E2:E4 to calculate the loan amount, the number of payment periods, and the monthly interest rate, respectively. Use cell references in all formulas.

13	In cell E5, enter a financial function to calculate the monthly payment. In cell E6, insert a financial function to calculate the cumulative total interest paid throughout the loan. Make sure the results display as positive numbers.
14	In cell C11, enter a formula to reference the date stored in cell B7. Insert a nested function in cell C12 to calculate the date for the next payment. Nest the YEAR, MONTH, and DAY functions within the DATE function. Add 1 to the month result. Copy the function to the range C13:C34.
15	In cell D11, enter a formula to reference the value stored in cell E2. Insert a formula in cell D12 that references the ending balance for the previous payment row (G11). Copy the formula in D12 to the range D13:D34.
16	In cell E11, enter a financial function to calculate the interest paid. Copy the formula to the range E12:E34. The result should be a positive value.
17	In cell F11, enter a financial function to calculate the principal payment. Copy the function to the range F12:F34. The result should be a positive value.
18	In cell G11, enter a formula to calculate the ending balance. Copy the formula to the range G12:G34. Adjust the width of column G, if needed, to display the values. Select the range D11:G34 and apply Accounting Number Format.
19	In cell I4 insert a financial function to calculate the present value of the total monthly rent you will collect for the 8 units for 30 years. Use the number of periods and monthly rate in the Summary Calculations section and the cell references in the What If section. The result should be a positive value.
