Morris-Meyer Mining Company must install $1.4 million of new machinery in its Nevada mine. It can obtain a bank loan for 100% of the required amount. Alternatively, a Nevada investment banking from that represents a group of investors believes that it can arrange for a lease financing plan. Assume that the following facts apply: The equipment falls in the MACRS 3-year class. The applicable MACRS rates are 33%, 45%, 15%, and 7%. Estimated maintenance expenses are $65,000 per year. Morris-Meyer's federal-plus-state tax rate is 45%. If the money is borrowed, the bank loan will be at a rate of 14%, amortized in 4 equal installments to be paid at the end of each year. The tentative lease terms call for end-of-year payments of $300,000 per year for 4 year. Under the proposed lease terms, the lessee must pay for insurance, property taxes, and maintenance. The equipment has an estimated salvage value of $300,000, which is the expected market value after 4 years, at which time Morris-Meyer plans to replace the equipment regardless of whether the firm leases or purchases it. The best estimate for the salvage value is $300,000, but it may be much higher or lower under certain circumstances. To assist management in marking the proper lease-versus-buy decision, you are asked to answer the following questions. Assuming that the lease can be arranged, should Morris-Meyer lease or borrow and buy the equipment? Explain. Round your answer to the whole number. Net advantage to leasing (NAL) is $ . (Input the minus sign if the cost of leasing the machinery is more than the cost of owning it.)

Carbon dioxide dissolved in soda can escape from the PET bottle slowly by means of diffusion. How long does it take for the soda to lose 10% of its original concentration? The following information might be useful: The inside surface of the bottle can be assumed to be saturated with carbon dioxide. The outside surface concentration can be neglected. It can be assumed that diffusion only takes place through the walls of the cylinder and not through the top or bottom. The bottle can be considered as a cylinder.

Diffusivity of CO2 in PET = 2×10-13 m2 /s;

Inner diameter of the bottle = 0.08 m;

Height of the bottle = 0.2 m;

Solubility limit of CO2 in PET = 10 kg CO2 per m3 of PET;

PET thickness = 0.5 mm;

Initial concentration of CO2 in cola = 7 g/L
