2.50 Fowler Co. produces two bearings: C15 and C19. Data regarding these bearings follow: C15 C19 Machine hours required per unit 2.00 Standard cost per unit: Direct material $ 2.50 $ 4.00 Direct labor 5.00 4.00 Variable overhead 3.00 2.50 Fixed overhead 4.00 5.00 Total $14.50 $15.50 Applied on the basis of direct labor hour ** Applied on the basis of machine hours * The company requires 8,000 units of C15 and 11,000 units of C19. Recently, management decided to devote additional machine time to other product lines, resulting in only 31,000 machine hours per year that can be dedicated to production of the bearings. An outside company has offered to sell Fowler the bearings at prices of $13.50 for C15 and $13.50 for C19. REQUIRED: a. Assume that Fowler decided to produce all C15s and purchase C19s only as needed. Determine the number of C19s to be purchased. b. Compute the net benefit to the firm of manufacturing (rather than purchasing) a unit of C15. Repeat the calculation for a unit of C19. c. Which component(s) (C15 and/or C19) should Fowler manufacture with the limited machine hours available? Why
