I need to know how to get the blank tax sheet to look like the filled tax sheet with formulas. This is the instuctions given by my professor.

-Cumulative interest payments for each year. Write a formula that automatically calculates this value for the corresponding periods so that it can be copied down for each year. Assume that the loans all begin in January so that no partial years need to be calculated. Note that to accommodate variable periods (the payments/yearare variableandcouldrepresentmonths,quarters,etc.)the beginningandendingperiods mustbecalculationsthatreferencethenumberof periodsperyearontheCalculator worksheet.

-Expected tax deduction for three different tax rates. In three adjacent columns, calculate the value of the expected tax deduction for tax rates of 15%, 28%, and 32% for the corresponding year (cumulativeinterestpayments*taxrate). Your formula for tax deduction should drag both down the column and across the row.

Total amount of interest paid. Sum the cumulative interest.

Pictures included are the empty tax sheet, the data I was given, and how the tax sheet should look, i am clueless how to get to the end result with formulas.
