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 $53,000$ machine$-$hours would be required for the periods estimated level of production. It also estimated $$1,000,000$ of fixed manufacturing overhead cost for the coming period and variable manufacturing overhead of $$4\mathrm{.}00$ per machine$-$hour.Because Delph has two manufacturing departmentsMolding and Fabricationit is considering replacing its plantwide overhead rate with departmental rates that would also be based on machine$-$hours. 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 Delphs cost of goods sold for the year?
