Mary is looking back at her work from last year, when she allocated the company$$s key process costs to its three products. She knows that the company has historically used the NRV method to allocate joint costs. Unfortunately, the printout that she has of the final allocations and supporting detail is only partially legible. You see, James accidently set the sprinklers off in the office last week, and Mary$$s printout was the recipient of most of that water. Here is a replication missing information with lowercase roman numerals. of what she could see from the printout; she noted Units produced $($available$)$ at split$-$off point Sales value per unit at split$-$off point Units produced $($available$)$ after further processing Final sales value per unit after further processing Further processing costs Allocated joint costs Ah $408$ $$8($i$)$ $$12$ $$2,900($ii$)$ Bay $204$ $$6340($iii$)$ $$640$ $$1,200$ Say $408$ $$4408$ $$10($iv$)$ $$1,800$ Total $1,020($v$)($vi$)($vii$)$ $$4,500$ $$6,000$
