1 An airline is considering two types of engine systems for use in its planes:

System A costs $100,000 and uses 40,000 gallons of fuel per 1,000 hours of operation at the average load encountered in passenger service.

S ystem B costs $200,000 and uses 32,000 gallons of fuel per 1,000 hours of operation at the average load encountered in passenger service.

Both engine systems have the same life and the same maintenance and repair record, and both have a three-year life before any major overhaul is required. Each system has a salvage value of 10% of the initial investment. If jet fuel costs $4.80 per gallon currently and fuel consumption is expected to increase at the rate of 6% per year because of degrading engine efficiency, which engine system should the firm install?

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?
