#### Activity 5-1

1. You are considering purchasing a car and want to compare prices offered by different manufacturers. Manufacturers have cars that start with a base model and then allow you to add accessories you want.  Go to five car manufacturer’s websites, choose a car you’d like, identify it’s base price, and then build the exact car you want with the options given.  Then prepare  a  worksheet  similar  to  that  shown  in Figure 5-12.

FIGURE 5-12

• In the range C3:C6, enter formulas that subtracts the values in column B from the values in column D.
• In cell D9, enter a function that determines the highest price in the range D3:D6.
• In cell D10, enter a function that determines the lowest price in the range D3:D6.
• In cell D11, enter a function that determines the average price in the range D3:D6.

Name the workbook as Car Purchase followed by your initials. Close the workbook.
