A factory employs 50 workers, 40 earn 450/hour and 10 earn 600/hour. What is the average hourly rate of pay

To find the average hourly rate of pay, we first need to calculate the total amount paid to all workers.

For the 40 workers earning 450/hour:
40 workers * 450/hour = 18,000 total amount paid to these workers

For the 10 workers earning 600/hour:
10 workers * 600/hour = 6,000 total amount paid to these workers

Total amount paid to all workers:
18,000 + 6,000 = 24,000

Now, we need to find the average hourly rate of pay by dividing the total amount paid by the total number of workers:

Average hourly rate of pay = Total amount paid / Total number of workers
Average hourly rate of pay = 24,000 / 50 = 480/hour

Therefore, the average hourly rate of pay for all workers in the factory is 480/hour.
