$8-21$ Straightforward four$-$variance overhead analysis. $($LO $4)$ Singh Company uses a standard cost system in its manufacturing plant for auto parts. The standard cost of a particular auto part, based on a denominator level of $4,000$ output units per year, included $6$ machine$-$hours of VMOH at $$8$ per hour and $6$machine$-$hours of FMOH at $$15$ per hour. Actual output achieved was $4,400$ units. VMOH incurred was $$245,000.$ FMOH incurred was $$373,000.$ Actual incurred machine$-$hours were $28,400.$Required Prepare an analysis of all VMOH and FMOH variances, using the four$-$variance analysis in Exhibit $8-11.$Prepare journal entries using the four$-$variance analysis.Describe how individual VMOH items are controlled from day to day. Also, describe how individual FMOH items are controlled. Check Figure: $1.$ Variable MOH rate variance, $$17,800$ U
