Final answer:
The annual capacity with a single eight-hour shift for Abert's fabricating production area is 3380 units/year.
Step-by-step explanation:
The annual capacity with a single eight-hour shift for Abert's fabricating production area can be calculated by multiplying the number of units produced per shift by the number of shifts in a year. In this case, the number of units produced per shift is given as 13. To find the number of shifts in a year, we need to consider the number of working days and the number of shifts per day. Assuming a standard 5-day work week, the number of working days in a year is 5 days per week * 52 weeks = 260 days. Since there is a single eight-hour shift, there will be 260 shifts in a year. Therefore, the annual capacity with a single eight-hour shift is 13 units/shift * 260 shifts/year = 3380 units/year.
