New lithographic equipment, acquired at a cost of $812,500 on March 1 of Year 1 (beginning of the fiscal year), has an estimated useful life of five years and an estimated residual value of $69,900. The manager requested information regarding the effect of alternative methods on the amount of depreciation expense each year. On March 4 of Year 5, the equipment was sold for $119,000.

Suppose life expectancy in years (l) is a function of two inputs, health expenditures (h) and nutrition expenditures (n) in hundreds of dollars per year. the production function is upper l equals ch superscript 0.40 baseline upper n superscript 0.60l=ch0.40n0.60. beginning with c = 1, a health input of $400400 per year (hequals=44) and a nutrition input of $400400 per year (nequals=44), show that the marginal product of health expenditures and the marginal product of nutrition expenditures are both decreasing. the marginal product of health expenditures when h goes from 44 to 55 is nothing, and the marginal product of health when h goes from 66 to 77 is nothing. (round your answers to three decimal places.)
