Final answer:
The total cost of the Supporting Assembly activity for Latif Corporation last year, calculated using the activity-based costing system, is $720.50 when rounding to the nearest whole dollar. However, this value does not exactly match any of the provided options, suggesting there may be an error in the options listed.
Step-by-step explanation:
To calculate the total cost of the activity "Supporting Assembly" for Latif Corporation last year using the activity-based costing system, we must determine the total amount of direct labor-hours used for the production and then apply the activity-based costing rate for Supporting Assembly.
First, we calculate the total direct labor-hours by multiplying the number of units by the direct labor-hours per unit: 1,100 units × 0.10 direct labor-hours per unit = 110 direct labor-hours. Next, we multiply the total direct labor-hours by the Supporting Assembly costing rate: 110 direct labor-hours × $6.55 per direct labor-hour = $720.50.
However, the options provided appear to be rounded to whole numbers. We would round $720.50 to the nearest whole number, which gives us $721. Thus, none of the provided options accurately reflect the calculated total cost. It seems there might be a mistake in the options given.
