Department A had 1,000 units in Work in Process that were 60% completed at the beginning of the period at a cost of $7,000. During the period, 4,000 units of direct materials were added at a cost of $8,200, and 4,500 units were completed. At the end of the period, 500 units were 40% completed. All materials are added at the beginning of the process. Direct labor was $28,700 and factory overhead was $4,510. The cost of the 500 units in process at the end of the period if the first-in, first-out method is used to cost inventories was:

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.)
