8. In column G , compute the sales commission earned on each property as a percentage of the total sales commissions. Also total column G and underline cell G25. 9. Input the appropriate formulas in cells C 28 , C 30 , and C 32 to compute the indicated statistics. 10. Format all numbers representing dollar amounts for commas and zero decimal places. Add a dollar sign to the first number in each column and totals. 11. Format the numbers in the "\% of Total Commissions" column to show percent signs and one decimal. 12.

Select the Home Financing Info tab. On this sheet, you will prepare a worksheet that Realtors can use to show home buyers what their monthly mortgage payment (principle and interest only) will be based on the home purchase price, down payment, and interest rate. To get you started, the sheet has data for a home already entered. Assume mortgage payments are made at the end of each period. 2. Input a formula in cell B12 to compute the loan amount by subtracting the down payment from the purchase price. This formula will need to be an =IF function since the down payment can be stated as either a dollar amount or a percentage. If the down payment is a percentage, you will need to convert that percentage into a dollar amount. For example, if a client purchases a $200 , 000 home and is going to put 10% down, the down payment is $20 , 000 and the loan amount will be $180 , 000 . Format cell B12 to show a $ and two decimal places. 3. Input a formula to compute the monthly payment amount in cell B18. Use the = PMT function. Remember that the interest rate is an annual interest rate but the =PMT function will need a monthly interest rate to compute a monthly payment. Also, be sure to calculate the total number of monthly payments in the =PMT function. The final number should be a positive number. You can achieve this by multiplying the = PMT function by 1 . .
