Western Electronics (WE) is reviewing the following data relating to a new equipment proposal: Net initial investment outlay After-tax cash inflow from disposal of the asset after 5 years $10,000 Present value of an annuity of $i at 128for 5 years Present value of $1 at 128 in 5 years $50,000 3.605 0.567 WE expects the net after-tax savings in cash outflows from the investment to be equal in each of the 5 years. What is the minimum amount of after-tax annual savings oncluding depreciation effects) needed to make the investment yield a 12% return (rounded to the nearest whole dollar)? $13,889.

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.)
