Don't understand what I did wrong for the first answer. I would appreciate some help understanding the correct way to do problem #1. I can figure the rest out myself after your help. Please and thank you.

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 51,000 machine-hours would be required for the period's estimated level of production. It also estimated $1,020,000 of fixed manufacturing overhead cost for the coming period and variable manufacturing overhead of $4.00 per machine-hour. Because Delph has two manufacturing departments-Molding and Fabricationit 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: Machine-hours Fixed manufacturing overhead cost Variable manufacturing overhead cost per machine-hour Molding 20,000 $ 760,000 $ 4.00 Fabrication 31,000 $ 260,000 $ 1.50 Total 51,000 $ 1,020,000 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: Job D-70 Direct materials cost Direct labor cost Machine-hours Molding $ 370,000 $ 200,000 15,000 Fabrication $ 320,000 $ 180,000 5,000 Total $ 690,000 $ 380,000 20,000 Job C-200 Direct materials cost Direct labor cost Machine-hours Molding $ 260,000 $ 180,000 5,000 Fabrication $ 280,000 $ 300,000 26,000 Total $ 540,000 $ 480,000 31,000 Delph had no underapplied or overapplied manufacturing overhead during the year. Required: 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?
