Suppose that you are planning to buy a boat in 20 years [to be entered into cell B2] for an amount of $100,000 [cell B1] at that time, and you earn an average annually compounding rate of return of 10% per year [to be entered into cell B3].

(a)	How much money would you need to invest today as a lump sum to achieve your goal [cell B5]? There are no additional deposits or payments. Use the PV function.

(b)

What is the correct formula (using 16 characters or less) that should be placed in cell B5? Note: There are to be NO numbers in the function call (apart from a 0 if appropriate), only cell references, or negative cell references where appropriate. Additional Note: For some reason, in the PV function, the f.v. represents an amount that is being paid out, not received. So the present value of something being paid out is a negative number. The correct answer to this question is the use of the PV function that returns the correct positive value.
