As operations manager, you are concerned about being able to meet sales requirements in the coming months. You have just been given the following production report: JAN FEB MAR APR Units produced 2,300 1,800 2,800 3,000 Hours per machine 325 200 400 320 Number of machines 3 5 4 4 Find the average of the monthly productivity figures (units per machine hour). (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average productivity 2.06 correct units per machine hour

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.)
