Final answer:
To calculate the selling price for Job A, combine direct materials, labor, and overhead costs then apply a 30% markup. The predetermined overhead rate is calculated, overhead costs are computed, and all costs are then summed and marked up. The final selling price does not match any of the provided options.
Step-by-step explanation:
To calculate the selling price for Job A, we first need to determine the total manufacturing cost, which includes direct materials, direct labor, and both fixed and variable manufacturing overhead costs. Afterward, we apply the 30% markup to set the selling price. Let's break down the calculation step by step.
Determine total machine-hours (MHs) used by Job A: 1,250 (Molding) + 1,750 (Finishing) = 3,000 MHs
Calculate the plantwide predetermined overhead rate by dividing the total estimated manufacturing overhead cost by the total estimated machine hours: $31,700 / 6,250 MHs = $5.072 per MH (rounded at two decimal places)
Compute total overhead costs for Job A: 3,000 MHs x $5.072/MH = $15,216 (rounded at two decimal places)
Add up all costs for Job A to find the total manufacturing cost: $15,900 (Direct materials) + $23,000 (Direct labor) + $15,216 (Overhead) = $54,116
Finally, calculate the selling price by adding a 30% markup to the total manufacturing cost: $54,116 x 1.30 = $70,350.80
Reviewing the options provided, none of the choices exactly match the calculated selling price of $70,350.80. Therefore, an error might be present, or the provided options could be incorrect.
