A welder can weld 2 angle irons together in 2 minutes.Over the course of an entire year she will assemble 1,000 units,each of which requires 3 such welds (i.e. ,welding two angle irons together is one step,and three such steps are needed per unit).If she is paid $25 an hour,how much is her annual welding labor cost?
A)$1,000
B)$1,250
C)$2,500
D)$3,000

To find the total time it will take the welder to assemble 1,000 units, we need to calculate the number of welds required:

3 welds per unit x 1,000 units = 3,000 welds

At a rate of 2 welds per 2 minutes, it will take the welder 3,000 minutes to complete all the welds:

3,000 welds ÷ 2 welds per 2 minutes = 3,000 minutes

To convert minutes to hours, we divide by 60:

3,000 minutes ÷ 60 minutes per hour = 50 hours

Finally, we can calculate the labor cost:

50 hours x $25 per hour = $1,250

Therefore, the correct answer is C.
