Kubin Company's relevant range of production is 20,000 to 23,000 units. When it produces and sells 21,500 units, its average costs per unit are as follows:

Direct materials $8.00 per unit
Direct labor $5.00 per unit
Variable manufacturing overhead $2.50 per unit
Fixed manufacturing overhead $6.00 per unit
Fixed selling expense $4.00 per unit
Fixed administrative expense $3.50 per unit
Sales commissions $2.00 per unit

Required:

a. What is the incremental manufacturing cost incurred if the company increases production from 21,500 to 21,501 units?
b. What is the incremental cost incurred if the company increases production and sales from 21,500 to 21,501 units?
c. Assume that Kubin Company produced 21.500 units and expects to sell 21,200 of them. If a new customer unexpectedly emerges and expresses interest in buying the 300 extra units that have been produced by the company and that would otherwise remain unsold, what is the Incremental manufacturing cost per unit incurred to sell these units to the customer?
d. Assume that Kubin Company produced 21,500 units and expects to sell 21,200 of them. If a new customer unexpectedly emerges and expresses interest in buying the 300 extra units that have been produced by the company and that would otherwise remain unsold, what incremental selling and administrative cost per unit is incurred to sell these units to the customer?

During the year, the delph company had no beginning or ending inventories and it started, completed, and sold only two jobs—job d-75 and job c-100. it provided the following information related to those two jobs: job d-75: molding fabrication total direct materials cost $ 375,000 $ 325,000 $ 700,000 direct labor cost $ 200,000 $ 160,000 $ 360,000 machine-hours 15,000 5,000 20,000 job c-100: molding fabrication total direct materials cost $ 300,000 $ 250,000 $ 550,000 direct labor cost $ 175,000 $ 225,000 $ 400,000 machine-hours 5,000 25,000 30,000delph had no overapplied or underapplied manufacturing overhead during the year. assume delph uses a plantwide overhead rate based on machine-hours.1-a. compute the predetermined plantwide overhead rate.1-b. compute the total manufacturing costs assigned to job d-70 and job c-200.1-c. if delph establishes bid prices that are 150% of total manufacturing costs, what bid price would it have established for job d-70 and job c-200? 1-d. what is delph's cost of goods sold for the year? assume delph uses departmental overhead rates based on machine-hours.2-a. compute the predetermined departmental overhead rates.2-b. compute the total manufacturing costs assigned to job d-70 and job c-200.2-c. if delph establishes bid prices that are 150% of total manufacturing costs, what bid price would it have established for job d-70 and job c-200? 2-d. what is delph's cost of goods sold for the year?
