PROJECT 2: WHAT-IF ANALYSIS

OBJECTIVE
The purpose of this project is to demonstrate your understanding of the following course concepts:

2. Using What-If Analysis tools.
3. Using Solver.
4. Using Scenarios.
5. Summary Reports.

PROJECT DESCRIPTION
PART 1
The automatic recalculation feature of Excel is a powerful tool that can be used to analyze worksheet data. What-if analysis is a decision-making tool in which changing input values recalculate formulas, in order to predict various possible outcomes. When new data is entered, Goal seek is a problem-solving method in which you specify a solution and then find the input value that produces the answer you want.

You are assisting Tony Sanchez, the office manager at Riverwalk Medical Clinic, with a disaster recovery plan for the medical records at the clinic. As part of that plan you are looking at two options for storing backup medical records. The first option is to purchase a storage facility, and the second is to use a third-party backup storage company that offers off-site small, medium, and large storage areas. In both cases, you want to keep your monthly payments below \$17,000. You decide to use Goal Seek to look at various interest rates for purchasing a storage facility and to use Solver to help find the best possible combination of third-party storage areas. You will be working with the attached file: EX_2.1.xlsx.

1. Open the fie EX_2.1xlsx and save it as Project2.1_Records.xlsx.
2. With the Purchase Sheet active, use Goal Seek to find the payment for an interest rate of 5.75% on a Loan amount of \$750,000 for 60 months. Use an additional loan amount of your choice with an interest rate of 6% to find the monthly payment for 48 months.
3.  Activate the Rental Sheet. Open Solver, then use the Set Objective To option to maximize the storage amount in cell B12. (Hint: Select Max in the Set the Objective To area.).
4. In Solver, use the quantity, cells B6:D6, as the changing cells.
5. Add a constraint to Solver specifying the quantity in cells B6:D6 must be integers.
6. Add a constraint specifying that the total monthly payment amount in cell B11 is less than or equal to 17,000.
7. Generate a solution using Solver and accept Solver’s solution.
8. Save the workbook and submit to the Assignment Folder.

PART 2
As a senior financial analyst at North Shore CPA Services, you are researching various options for financing a \$250,000 loan for the purchase of a new estate-planning facility. You haven’t decided whether to finance the project for three, four, or five years. Each loan term carries a different interest rate. To help with the comparison, you summarize these options using a Scenario Summary. You will be working with the file EX_2.2.xls.

1. Open the fie EX_2.2.xlsx and save it as Project2.2_Loans.xlsx.
2. Create cell names for cells B4:B11 based on the labels in cells A4:A11, using the Create Names from Selection dialog box.
3. Use Scenario Manager to create scenarios that calculate the monthly payment on a loan amount of your choice under the three sets of loan possibilities listed below in Figure 1. For instance, in Figure 2 below, the loan amount of \$250,000 was used. Note: You cannot use the loan amount of \$250,000. (Hint: Create three scenarios, using cells B5:B6 as the changing cells.
