3. The following information is related to manufacturing overhead gests. MOH cost pool includes depreciation (fixed, 10000 dollars per month), indirect material (variable, 2 dollars per unit) and supervision (semi-variable). During the last six months, the highest activity level was in May (1720 units produced) and total MOH cost was $35300. The lowest activity level was in March (1320 units produced) and total MOH cost was $31300, a.) Write the cost formula of supervision (use the high-low method), b.) Estimate Total MOH for July ( 1800 units produced) by using the data of the year's first six months. 3. The following information is related to manufacturing overhead gests.
