The devon motor company produces motorcycles. during april, the company purchased 8,000 batteries at a cost of $10 per battery. devon withdrew 7,600 batteries from the storeroom during the month. of these, 100 were used to replace batteries in motorcycles used by the company's traveling sales staff. the remaining 7,500 batteries withdrawn from the storeroom were placed in motorcycles being produced by the company. of the motorcycles in production during april, 90% were completed and transferred from work in process to finished goods. of the motorcycles completed during the month, 30% were unsold at april 30. there were no inventories of any type on april 1.

determine the cost of batteries that would appear in each of the following accounts at april 30 (omit the "$" sign in your response):

(a) raw materials

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
