Original source: for those who can't afford to be fussy about status or pay, there are of course plenty of jobs in america. hundreds of thousands of immigrants crowd into the country every year to work in lawn maintenance, on construction crews, or as housecleaners, nannies, and meat packers. even in the absence of new job creation, high turnover in the low-wage job sector guarantees a steady supply of openings to the swift and the desperate. to white-collar job seekers, these are known as "survival jobs"--something to do while waiting for a "real" job to come along.

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.)
