A Sikho High School has 12 educator assistants and 8 general assistants. Each earns R3 500/month and contributes 1% to UIF. Questions: (1.1.1) Write UIF in full. (1.1.2) Calculate monthly UIF contribution. (1.1.3) Define 'net salary'. (1.1.4) Calculate net salary. (1.1.5) Ratio of general to educator assistants. (1.2) Weather prediction for East London: (1.2.1) Order min temps descending. (1.2.2) Discreet or continuous temp? (1.2.3) Second highest max temp. (1.2.4) Day with lowest min temp.

Question 1

1.1 Total monthly UIF contribution per employee

Step 1: Employee's contribution = $1\%$ of gross salary.

Step 2: Employer's contribution = $1\%$ of gross salary.

Step 3: Total UIF contribution = employee's contribution + employer's contribution
$= 1\% of gross salary + 1\% \text{ of gross salary}$
$= 2\% \text{ of gross salary.}$

$\mathbf{2\% of gross salary per month}$

1.2 Definition of "net salary"

Net salary is the gross salary after deducting the employee's $1\%$ UIF contribution.

1.3 Ratio of general assistants to educator assistants

Step 1: Ratio = number of general assistants : number of educator assistants
$= 4 : 10$

Step 2: Divide both sides by $2$
$= 2 : 5$

$\boxed{2 : 5}$

Question 2
Weather data for first week of March $2026$ ($\circ\mathrm{C}$):

| Day | Max | Min | |------|-----|-----| | Sun | $22$ | $14$ | | Mon | $20$ | $19$ | | Tue | $18$ | $10$ | | Wed | $20$ | $19$ | | Thu | $17$ | $9$ | | Fri | $19$ | $20$ | | Sat | $26$ | $21$ |

2.1 Arrange minimum temperatures recorded in decreasing order

Minimum temperatures: $14^\circC, 19^\circC, 10^\circC, 19^\circC, 9^\circC, 20^\circC, 21^\circ\mathrm{C}$

Step 1: Order from highest to lowest
$21^\circC,\ 20^\circC,\ 19^\circC,\ 19^\circC,\ 14^\circC,\ 10^\circC,\ 9^\circ\mathrm{C}$

$\boxed{21^\circC,\ 20^\circC,\ 19^\circC,\ 19^\circC,\ 14^\circC,\ 10^\circC,\ 9^\circC}$

2.2 Second highest maximum temperature this week

Step 1: Maximum temperatures: $22^\circC,\ 20^\circC,\ 18^\circC,\ 20^\circC,\ 17^\circC,\ 19^\circC,\ 26^\circ\mathrm{C}$

Step 2: Highest = $26^\circ\mathrm{C}$ (Saturday)

Step 3: Second highest = $22^\circ\mathrm{C}$ (Sunday)

$\boxed{22^\circ \textrm{C (Sunday)}}$

2.3 Day with the lowest minimum temperature this week

Step 1: Minimum temperatures:
Sun: $14^\circ\mathrm{C}$
Mon: $19^\circ\mathrm{C}$
Tue: $10^\circ\mathrm{C}$
Wed: $19^\circ\mathrm{C}$
Thu: $9^\circ\mathrm{C}$
Fri: $20^\circ\mathrm{C}$
Sat: $21^\circ\mathrm{C}$

Step 2: Lowest = $9^\circ\mathrm{C}$ (Thursday)

$\boxed{\textrm{Thursday}}$
