1. The Smith family is planning for their daughter's education. She just turner 5 years old and will be 18 when she starts university. They are planning to make monthly deposits of $300 into an RESP(Registered Educational Savings Program).Deposits are made at the end of each month.They anticipate that they can earn a return of 4.8%annual interestcompounded monthlyon their RESP. When their daughter starts university, she will withdraw$20,000 to pay for her 1styear. The balance will be paid out at the end of each year (end of 1st, end of 2ndand end of 3rd) in equal amounts to pay for the subsequent years. During those 3 years the Smith's hope that the account will earn 6%annual interestcompoundedannually. How much can their daughter expect to withdraw each year?

2. Smithson Foods is looking at purchasing new equipment for mixing pastry to make pies. Two different manufacturers are being considered. TheJorgan'sMixmaster costs $24,000 and requires annual maintenance costs of $1,950 per year. TheXiaolongMixer costs $20,000 but with annual maintenance costs of $$2,600 per year. Assume that maintenance costs are incurred at the end of the year, including the final year. Regardless of which machine is chosen, Smithson intends to replace the mixer in 7 years. In 7 years it is estimated that a usedJorgan'scan be sold for $6,500 whereas a usedXiaolongwould sell for $5,800.If Smithson uses a rate of 18%compounded annuallyto evaluate equipment investments, which machine should they choose? (which machine has lower NPV of costs?)

3. Graves Lighting in considering the replacement of a metal stamping machine at their facility in Dayton, Ohio. Machine A will cost $37,000, have annual maintenance costs of $2,800 (payable at the end of the year), need a major refit after 8 years costing another $7,000, and have a resale value of $11,000 at the end of its15 yearlife. Machine A offers many productivity savings over the machine it replaces and is expected to generate savings of $9,000 per year (assume this accrues at the end of the year).

The alternative is to buy the less expensive Machine B at a cost of $27,000. The annual maintenance will only be $2,000 per year. It will also need a refit after 8 years at $5,000 and have a resale value of $8,000 at the end of its15 yearlife. It is not as efficient as Machine A and will generate savings of just $7,000 per year.

If Graves uses an interest rate of 15%compounded annuallyto evaluate projects, which is the better choicebased upon Net Present Value (NPV)?
