Assume that you are investing $6,000 in a savings plan today and will make additional contributions of $200 per quarter. The plan pays 5% interest per year compounded quarterly. Formula for savings in 5 years =FV(.05/4, 5*4, ‐200, ‐6000,0) 16. Excel formula to determine the yearly interest rate being charged by the bank on a $375,000, 30‐year mortgage. You make a monthly mortgage payment of $3,000 and the value of the loan at the end of 30 years is 0. Interest is compounded monthly. =RATE(30*12,‐3000,375000,0,0) 17. You are buying a car for $23,500 with a $3,000 down payment, and you are borrowing the rest from a bank at 6.0% annual interest compounded monthly. Your monthly payments are $370.Write an Excel formula to determine the number of years it will take you to pay off this loan. =NPER(.06/12,‐370,‐20500,0) 18. Consider a $100,000 mortgage at 5% annual interest compounded monthly, to be paid back over the next 15 years. The loan will have a $5,000 balloon payment due at the end of the loan. Write an Excel formula to determine the payment that must be made each month on this loan. =PMT(.05/12,15*12,100000,‐5000) 19. Assume that you have been left an inheritance and want to save part of it toward the purchase of a car upon graduation, which is three years from now. Write an Excel formula to determine the amount of money you need to inves t now to have $15,000 at the end of the three‐year period. Assume that you will place this money in a CD that pays 3% interest compounded quarterly and that you will be making no additional deposits into this account. =PV(.03/4, 3*4, 0, 15000) 20. Write an Excel formula to determine the amount of money that can be depreciated each year, using straight line depreciation, for a new packaging machine purchased by your company. The machine originally cost $250,000 and has a useful life of 10 years and an estimated salvage value of $10,000. =‐(SLN(250000,10000,10)) Chapter 7 1. List and describe the steps you would take to create a structured list of data from a text file that contains values stored on separate lines. use the CONCATENATE, TRIM, RIGHT, and FIND functions to combine multiple text strings into a single text string, to trim unnecessary spaces from a text string, to find and extract characters from a text string, and to find specific characters in a text string. 2. Why should you remove unnecessary spaces from data imported from another source? How do you remove unnecessary spaces from a text string? May cause errors within Excel, using the TRIM function. 3. How do the FIND and SEARCH functions work, and how are they different? The FIND function returns the starting position of one text value within another text value and it is case‐sensitive. SEARCH function does the same thing as FIND but it is not case‐sensitive. 4. What options are available for parsing data when you use the Convert Text to Columns Wizard? i. Identify the character that delimates the data. In comma‐delimited files, commas separate the data. Another common way is the tab character. ii. Set field widths to identify the breaks between data that appears in columns. 5. What are the advantages and disadvantages of using the Subtotal tool to analyze data? Advantages are that it creates summary reports that quickly organize data into categories with subtotal calculations and allows you to collage and expand the level of detail in a report The disadvantages are that it works only with one ca tegory and one subtotal calculation at a time. 6. What is the difference between an unstructured list and an Excel list? Excel lists are in a structured format, you can use the filter feature to sort through the data using different methods. 7. List and describe the six available options when using the AutoFilter feature in an Excel Table. i. Sort A to Z – sorts data in ascending order ii. Sort Z to – sorts in descending order iii. Sort by Color—if cells are manually or conditionally changed to have background color, it filters these colors iv. Clear Filter From—removes any filters and restores original data v. Text Filters—filters alphanumeric text by specific characters vi. Number Filters vii. Date Filters –filters by date and time values using comparison operators viii. Custom Filter—all filters include option to filter custom 8. What is the primary advantage of storing data in a database and importing that data into Excel? It ensures that your data is secured and protected but can be analyzed using a spreadsheet easily, thus reducing re dundancy. 9. Explain the steps you must take to import data stored in an Access database into Excel. i. Open a workbook where you want to import the database data. ii. Select the first blank cell where you want the data to appear, and then click the From Access button in the Get External Data group on the Data tab on the Ribbon. The Select Data Source dialog box opens. 10. What is the Query Wizard and when would you use it? It lets you choose your data source and select the database table and fields you want to
