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

1.2 How much will she get per week if her salary increases by 12%?

To calculate the increased salary, we can multiply Ruth's current salary by 1.12 (to account for the 12% increase):

Increased salary = N$3600 * 1.12 = N$4032

Therefore, Ruth will get N$4032 per week if her salary increases by 12%.

To calculate Ruth's new weekly salary after a 12% increase, follow these steps:

Step 1: Calculate the 12% increase:
12% of N$3600 = (12/100) * 3600 = N$432

Step 2: Add the increase to her original salary:
N$3600 + N$432 = N$4032

Therefore, Ruth's new weekly salary after a 12% increase will be N$4032.
