Five dollar stores (fds) sells merchandise for cash. it began 2021 with a refund liability of $0, made sales of $1,000,000 during 2021 which cost fds $600,000 (or 60%), estimates that 1% of all sales will be returned, and experiences $8,000 of returns during 2021. when accruing its estimate of remaining returns at the end of 2021, fds would debit sales returns and credit the refund liability for:

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
