Landen Corporation uses a joborder costing system. At the beginning of the year, the company made the following estimates: Direct labor-hours required to Support estimated production 140,000 Machine-hours required to support estimated production 70,000 Fixed manufacturing overhead cost $784,000 Variable manufacturing overhead cost per direct laborhour $ 2.00 Variable manufacturing overhead cost per machinehour S 4.00 [ During the year, Job 550 was started and completed. The following information is available with respect to this job: Direct materials $ 175 Direct labor cost $ 225 Direct labor-hours 15 Machine-hours 5 l Required: 1. Assume that Landen has historically used a plantwide predetermined overhead rate with direct labor-hours as the allocation base.Under this approach: a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost of Job 550. c. If Landen uses a markup percentage of 200% of its total manufacturing cost, what selling price would it establish for Job 550? 2. Assume that Landen's controller believes that machinehours is a better allocation base than direct laborhours. Under this approach: a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost of Job 550. c. If Landen uses a markup percentage of 200% of its total manufacturing cost, what selling price would it establish for Job 550? 1n_____n A._____ E_L_______IE_L_ __-___|_;:___ L_ n _|__:___- _|____ n_.___| .__._._ n___I_A___.___I n_.__|____n n ______________ n _-__.___| m 1.

(Round your intermediate calculations to 2 decimal places. Round your Predetermined Overhead Rate answers to 2 decimal places and all other answers to the nearest whole dollar.) 1. Direct laborhours: a. Predetermined overhead rate per DLH b. Total manufacturing cost of Job 550 0. Selling price 2. Machine-hours: a. Predetermined overhead rate per MH b. Total manufacturing cost of Job 550 0. Selling price
