Last Chegg expert gave me an incorrect answer. The Predetermined overhead rate is not 21.55 . Please answer only if you know, thank you!

Exercise 2-15 (Algo) Plantwide and Departmental Predetermined Overhead Rates; Job Costs [LO2-1, LO22, LO2-3, LO2-4] [The following information applies to the questions displayed below.] Delph Company uses a job-order costing system with a plantwide predetermined overhead rate based on machine-hours. At the beginning of the year, the company estimated that 55,000 machine-hours would be required for the period's estimated level of production. It also estimated $1,000,000 of fixed manufacturing overhead cost for the coming period and variable manufacturing overhead of $5.00 per machine-hour. Because Delph has two manufacturing departments-Molding and Fabrication-it is considering replacing its plantwide overhead rate with departmental rates that would also be based on machine-hours. The company gathered the following information to enable calculating departmental overhead rates: During the year, the company had no beginning or ending inventories and it started, completed, and sold only two jobsJob D-70 and Job C-200. It provided the following information related to those two jobs: Delph had no underapplied or overapplied manufacturinq overhead during the vear. 1. Assume Delph uses plantwide predetermined overhead rates based on machine-hours. a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost assigned to Job D-70 and Job C-200. c. If Delph establishes bid prices that are 150% of total manufacturing costs, what bid prices would it have established for Job D-70 and Job C-200? d. What is Delph's cost of goods sold for the year? Complete the question by entering your answers in the tabs given below. Assume Delph uses plantwide predetermined overhead rates based on machine-hours. Compute the plantwide predetermined overhead rate. (Round your answer to 2 decimal places.)
