The Green Revolution was based in part on extensive experimentation. The following data illustrates the relationship between nitrogen fertilizer (in pounds of nitrogen) and the output of a particular type of wheat (in bushels). Each observation is based on one acre of land and all other relevant inputs to production (such as water, labor, and capital) are held constant. The fertilizer levels are 20, 40, 60, 80, 100, 120, 140, and 160, and the associated output levels are 47, 86, 107, 131, 136, 148, 149, and 142. Use Excel to estimate the short-run production function showing the relationship between fertilizer input and output. (Hint: Use trendline option to regress output on fertilizer input. Try a linear function and try a quadratic function and determine which function fits the data better). Does fertilizer exhibit the law of diminishing marginal returns? What is the largest amount of fertilizer that should ever be used, even if its free?

White company has two departments, cutting and finishing. the company uses a job-order costing system and computes a predetermined overhead rate in each department. the cutting department bases its rate on machine-hours, and the finishing department bases its rate on direct labor-hours. at the beginning of the year, the company made the following estimates: department cutting finishing direct labor-hours 6,000 30,000 machine-hours 48,000 5,000 total fixed manufacturing overhead cost $ 264,000 $ 366,000 variable manufacturing overhead per machine-hour $ 2.00 " variable manufacturing overhead per direct labor-hour " $ 4.00 required: 1. compute the predetermined overhead rate for each department. 2. the job cost sheet for job 203, which was started and completed during the year, showed the following: department cutting finishing direct labor-hours 6 20 machine-hours 80 4 direct materials $ 500 $ 310 direct labor cost $ 108 $ 360 using the predetermined overhead rates that you computed in requirement (1), compute the total manufacturing cost assigned to job 203. 3. would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide predetermined overhead rate based on direct labor-hours, rather than using departmental rates?
