Which salary plan would you choose and why? Write down your initial reaction.
Use a spreadsheet or some other method to figure out which salary plan is better.
When using a spreadsheet, create three columns, one for the week number, one for plan A, and one for plan B. When creating the rule for plan B, remember that the salary is doubling each week, and that the first week's salary is one penny, not one dollar. Close Tip
Are you surprised that the second salary grew so rapidly? Use the spreadsheet to determine how much money you would make from plan B in 40 weeks.
To make a column wider, click and hold down on the right edge of the column heading letter, then drag the mouse to the right. Close Tip
