Final answer:
The budgeted MOH rate using one plant-wide pool based on Direct Labor (DL) cost is approximately $0.80.
Step-by-step explanation:
The budgeted MOH rate using one plant-wide pool based on Direct Labor (DL) cost can be calculated by dividing the total manufacturing overhead (MOH) costs by the direct labor cost. In this case, the total MOH costs are the sum of rent for the factory ($74,000), factory utilities ($40,800), quality control salaries ($53,700), and janitorial salaries ($36,200), which totals $204,700. The direct labor cost is the sum of assembly line workers' wages ($245,700), tennis ball coating costs ($7,000), and tennis ball core costs ($4,600), which totals $257,300. Therefore, the budgeted MOH rate is $204,700 divided by $257,300, which equals approximately $0.796 or $0.80. So, the correct option is 3) $7.92.
