Ruth is paid N$ 3600 for a 5-day week working 8 hours per day.

1.1 Calculate how much she gets per hour.

To calculate how much Ruth gets per hour, we need to divide her weekly pay by the total number of hours she works in a week.

Total number of hours Ruth works in a week = 5 days * 8 hours per day = 40 hours

Now we can calculate her hourly rate by dividing N$ 3600 by 40 hours:

Hourly rate = N$ 3600 / 40 hours = N$ 90/hour

To calculate how much Ruth gets per hour, we can divide her total pay by the number of hours worked.

Total pay = N$ 3600
Number of hours in a week = 5 days * 8 hours/day = 40 hours

Per hour rate = Total pay / Number of hours
Per hour rate = N$ 3600 / 40 hours

Per hour rate = N$ 90
