Bill moved in with his mother a few years back. She is now thinking that this was a bad idea so she has promised to give him $10,000 when he leaves the house forever toward the downpayment on a new home. Bill had planned to leave in five year time. However, the offer from his mother has him thinking that he could leave one year earlier than he had planned. As a result, the present value of this offer will:

• be greater than $10,000.

• remain constant.

• decrease.

• increase.

• equal $10,000.
