ZIP inc is a scooter manufacturer, using one (plant-wide) rate to allocate manufacturing overhead (MOH) to its products. However, starting in January 2023 , ZIP decides to switch to ABC costing to allocate the manufacturing overhead costs. The estimated manufacturing overhead costs for the upcoming year (2023), and the cost driver for each manufacturing activity, are shown in the table below. Total estimated activity for 2023: 1,200 preparation hours; 5,000 machine hours, and 4,500 direct labour hours. The rate of pay for all direct labour employees is $36 per hour. 1b Assume now that ZIP Inc is using ABC Costing in 2023. Calculate the MOH allocation rates for each activity, using the data above. Label your answers clearly. (3 pts) 1c It is now January 2023. ZIP receives an order (Job \#55) from a customer for 10 scooters. This order will use 24 prep hours, 70 machine hours and 100 direct labour hours. Additionally, the direct materials cost will total $5,000. Using ABC Costing, determine the total job cost of Job \#55. (6 pts) 1d If ZIP Inc had used the plant-wide MOH allocation rate for Job \#55, would the job have been over- or under-costed? In your answer, calculate the dollar amount by which the plant-wide rate would have under or over-costed the job. (4pt) 1e Why is accurate job costing important to the manager?
