A welder can weld 2 angle irons together in 2 minutes.Over the course of an entire year he will assemble 1,000 units,each of which requires 2 such welds (i.e. ,welding two angle irons together is one step,and two such steps are needed per unit).If he is paid $30 an hour,how much is his annual welding labor cost?
A)$250
B)$500
C)$1,000
D)$2,000

Quizplus · Accepted Answer

The welder takes 2 minutes to weld 2 angle irons together, which means it takes him 1 minute to weld one.

In 1,000 units, there will be 2,000 such welds (2 for each unit).

If he takes 1 minute per weld, then he will take a total of 2,000 minutes to complete all the welds (1,000 units x 2 welds per unit x 1 minute per weld).

This is equivalent to 33.33 hours (2,000 minutes ÷ 60 minutes per hour).

At a rate of $30 per hour, his labor cost will be $1,000 (33.33 hours x $30 per hour).

Therefore, the correct answer is D.
