$8-21$ STRAIGHTFORWARD FOUR$-$VARIANCE OVERHEAD ANALYSIS. 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
