Maintenance money for an athletic complex has been sought. Mr. Kendall, the Athletic Director, would like to solicit a donation to cover all future expected maintenance costs for the building.
These maintenance costs are expected to be $1.2 million each year for the first five years, $1.6 million each year for years 6 through 10, and $1.9 million each year after that. (The building has an
indefinite service life.)
If the money is placed in an account that will pay 7% interest compounded annually, how large should the gift be?
Click the icon to view the interest factors for discrete compounding when i = 7% per year.
The gift should be $31.35 million. (Round to two decimal places.

A client has an existing CAD/CAM system that costs $95,000 per year to lease (payable at the end of each year of use) and a new contract the client is considering entering will fix the price for over the next four years. The client is also considering purchasing a CAD/CAM system to replace its currently leased system (rather than renewing / entering a new lease contract). The new system will cost $450,000 to purchase and install. The system has an estimated life of five years, when it is expected to become obsolete, but it will have a salvage value of $25,000. The interest rate is projected to be 6% per year during the life of the project.
a. Draw a cash flow diagram for the next four years for the existing system (leased system) and a separate cash flow diagram for the system that is being considered for purchase.
b. For each option (leasing and buying), calculate the value of all cash receipts and disbursements at the end of the third year.

A manufacturing company leases a building for $100,000 per year for its manufacturing facilities. In addition, the machinery in this building is being paid for in installments of $20,000 per year. Each unit of the product produced costs $15 in labor and $10 in materials. The product can be sold for $40. what are the following
1. How many units per year must be sold for the company to breakeven?
2. If 10,000 units per year are sold, what is the annual profit?
3. If the selling price is lowered to $35 per unit, how many units must be sold each year for the company to earn a profit of $60,000 per year?

- solve it using manual computation; do not use Microsoft Excel The Ajax Corporation has an overhead crane that has an estimated remaining life of 10 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 10% per year in evaluating investment alternatives. Should the company replace the old crane?arrow_forwardThe president's executive jet is not fully utilized. You judge that its use by other officers would increase direct operating costs by only $37,000 a year and would save $100,000 a year in airline bills.

Concrete incorporated estimates that this expansion would lead to an increase in revenues of $44,000 starting at the end of first year and decreasing at rate of 2% per year due to decrease in the machine's productive capacity while the O & M would cost $10,000 per year increasing at rate of 5% per year.
