Answer:
18,900 units were produced during the period
Step-by-step explanation:
General, selling, and administrative expenses does not make part of the Manufacturing Overhead Costs so the calculation of the units is as follow:
(Direct materials + Wages for production workers + Lease payments, utility costs, and depreciation on factory equipment) / the average cost to produce one unit
( $28,810 + $49,900 + $13,900) / $4.90 = $92.610,00 / $4.90 = 18,900
