Question $1$: Flow of Costs with Proration and $100\%$ COGS Adjustments:

James Michael schedules autograph signings for football fans and creates posters to sell at eachsigning. James uses a normal$-$costing system with two direct cost pools, labor and materials, andone indirect cost pool, general overhead. General overhead is allocated to each signing based on$70\%$ of labor cost. Actual overhead equaled allocated overhead in April $2023.$ Actual overhead inMay was $$1,000.$ All costs incurred during the planning stage for a signing and during thesigning are gathered in a balance sheet account called $$Signings in Progress $($SIP$.)$ When asigning is completed, the costs are transferred to an income statement account called, $$Cost ofCompleted Signing $($CCS$).$ Following is cost information for May, $2023$:From Beginning SIPIncurred in MayAthleteMaterialLaborOverheadMaterialLaborOverheadssBenji Binkleman$$500$$$800?$$$300$$$200?$Ravi Patel$$300$$$1,00?$$$700$$$200?0$Rebecca Rampton$$600$$$500?$$$500$$$900?$The signings for Benji Binkleman and Ravi Patel were completed in May.
