Fiske Corporation manufactures a popular regional brand of kitchen utensils. The design and variety have been fairly constant over the last three years. The managers at Fiske are planning for some changes in the product line next year, but first they want to understand better the relation between activity and factory costs as experienced with the current products. Discussions with the plant supervisor suggest that overhead seems to vary with labor-hours, machine-hours, or both. The following data were collected from the last three years of operations: Labor-Hours Factory costs $ 3,388,671 Quarter Machine-Hours 1 18,850 14,905 2 18,590 15,477 3,425,136 3 17,480 16,720 3,617,144 4 19,240 15,983 3,573,240 5 21,280 17,501 3,812,284 6 19,630 17,369 3,777,312 7 19,240 15,290 3,531,726 8 18,850 14,366 3,369,102 9 18,460 15,994 3,512,487 10 20,670 16,995 3,730,734 11 17,550 14,278 3,230,115 12 18,460 18,444 3,723,786 Required: a.
