  4. D

Answer

The facility's production rate is 3030 shirts per hour.
To find the hourly production rate, first determine the total hours worked by multiplying the number of days by the hours per shift (5 days×8 hours=40 hours5 \text{ days} \times 8 \text{ hours} = 40 \text{ hours}). Then, divide the total production by the total hours (1,200 shirts÷40 hours=30 shirts per hour1,200 \text{ shirts} \div 40 \text{ hours} = 30 \text{ shirts per hour}).

Step-by-Step Solution

1
Calculate the total number of hours the facility operated.
5 days×8 hours/day=40 hours5 \text{ days} \times 8 \text{ hours/day} = 40 \text{ hours}
To find the hourly rate, the total time must be expressed in hours.
2
Divide the total number of shirts produced by the total number of hours.
1,200÷40=30 shirts per hour1,200 \div 40 = 30 \text{ shirts per hour}
Dividing total quantity by total time yields the unit rate.
