Final answer:
Keketso's gross wage per week is R2800. The manager earns R15,000 per month.
Step-by-step explanation:
To calculate the gross wage, we need to add the normal wage to the overtime wage. In Keketso's case, his gross wage amounts to R1800 (normal wage) + R1000 (overtime wage) which equals R2800 per week.
As for the manager's earnings, we first need to understand that a year typically has 12 months. So, to find out the monthly earnings, we would divide the annual salary by 12. Therefore, R180,000/12 gives us a monthly salary of R15,000 for the manager.
