Mr. Pine, a self-employed engineer in Boston, traveled to Chicago in order to attend a course on new engineering techniques. He spent 2 weeks attending the course and remained in Chicago for an additional 6 weeks on personal matters. The air flight cost $200, hotel $600, meals $320, and the tuition for the course $500. How much of these expenses may Mr. Pine deduct on his return

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.)
