We are given that the Manual word processor operator makes $11.50 an hour.
We need to find out how much will he earn If he worked 52 hours per week .
so use the following formula:
Operator gross earning = 11.5 x n ... (where n represent number of hours)
= 11.5 x 52
= $598
This means the operator earns $598 per week or per 52 hours worked
