An eight-station rotary-indexing machine performs machining operations at seven workstations, and the eighth station is used for unloading and loading parts. The longest process time is 1.55 min and the loading/unloading time is less than this. It takes 9.0 sec to index the machine between workstations. Stations break down with a frequency of 0.005, which is considered equal for all eight stations. When breakdowns occur, it takes an average of 7.0 min to diagnose the problem and make repairs. The starting work part costs $3.50 per unit. Operating cost of the indexing machine is $96/hr, and tooling cost is $0.38 per piece. Determine (a) line efficiency, (b) average hourly production rate, and (c) completed part cost.

Peninsula products has just applied for a loan at your bank. when reviewing peninsula's books for the year that just ended, you notice that the firm uses the fair value option for its bonds payable. you also see that the firm recorded a $55,000 debit in its bonds payable account and a $55,000 credit in its unrealized holding gain or loss"income account. over that same period, interest rates decreased by about 0.5 percent. how should this information affect the bank's decision as to whether to grant peninsula a loan? a : the bank should strongly consider giving a loan to peninsula because the changes in firm's bonds payable and unrealized holding gain or loss"income accounts suggest that peninsula has seen an increase in its credit rating over the past year. b : the bank should put little emphasis on the changes in peninsula's bonds payable and unrealized holding gain or loss"income accounts because these changes are likely the result of the rise in interest rates. c : the bank should hesitate before giving a loan to peninsula because the changes in firm's bonds payable and unrealized holding gain or loss"income accounts suggest that peninsula has seen a decline in its credit rating over the past year. d : the bank should put little emphasis on the changes in peninsula's bonds payable and unrealized holding gain or loss"income accounts because these changes are likely unrelated to either interest rates or the firm's credit rating.
