Assume you have a total of $200,000 to invest in two corporate stocks identified as Z1 and Z2. The overall rate of return you require on the $200,000 is 26% per year. (a) If $40,000 is invested in Z2 with an estimated i * Z2 of 14% per year, what value must i * Z1 exceed to realize at least 26% per year? (b) If the best return expected from the Z1 stock is 27%, determine the threshold level of investment in Z2 to maintain an overall ROR of 26% per year. Solve by hand or using Goal Seek, as instructed.

The ford motor company is considering three mutually exclusive electronic stability control systems for protection against rollover of its automobiles. The investment (study) period is four years, and MARR is 12% per year. Data for the fixture costs of the systems are as follows:
plot the AW of each alternative against MARR as the MARR varies across this range:4%, 8%, 12%, 16%, and 20%. What can you generalize about the range of the MARR for which each alternative is preferred?

- A carton packaging manufacturer considers 2 alternative machines in its production process, namely automatic machines and semi-automatic machines. The price of the automatic machine is Rp. 23 billion with an estimated salvage value of Rp. 4M after 10 years. If an automatic machine is selected, an operational cost of Rp. 12 million per hour and a maintenance fee of IDR 3.5 billion per year. While the engine output is 8 tons per hour. Semi-automatic machines can be purchased for Rp. 8M with an estimated useful life of 5 years, without salvage value. If a semi-automatic machine is selected, an operational cost of Rp. 24 million per hour and a maintenance fee of Rp. 1.5M per year. While the engine output is 6 tons per hour. Question :If the MARR used is 10%, calculate:a. How many tons of product must be produced each year so that automatic machines are more economical than semi-automatic machines? b.

Because both forklifts perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The electric-powered truck will cost more, but it will be less expensive to operate; it will cost $21,500, whereas the gas-powered truck will cost $17,960. The cost of capital that applies to both investments is 13%. The life for both types of truck is estimated to be 6 years, during which time the net cash flows for the electric-powered truck will be $6,860 per year, and those for the gas-powered truck will be $4,600 per year. Annual net cash flows include depreciation expenses. Calculate the NPV and IRR for each type of truck, and decide which to recommend. Do not round intermediate calculations.
