Right, let's go. 2.1.1 Step 1: Locate the tax number on the salary advice. The tax number is found under the "Tax number" field. $$ \text{Tax number} = 17238723 $$ The tax number is $\boxed{\text{17238723}}$. 2.1.2 Nett salary, also known as take-home pay, is the amount of money an employee receives after all deductions (such as taxes, pension contributions, and other allowances) have been subtracted from their gross salary. It is the actual amount paid to the employee. 2.1.3 Step 1: Identify all individual deduction amounts from the salary advice. • TAX RSA: R8 780,74 • GEPF: R2 753,92 • GEMS: R2 131,00 • SACE: R16,50 • Union: R109,24 Step 2: Sum these individual deduction amounts. $$ \text{Total Deductions} = 8780,74 + 2753,92 + 2131,00 + 16,50 + 109,24 $$ $$ \text{Total Deductions} = 13791,40 $$ The sum of the individual deductions is R13 791,40, which matches the "Deductions" amount on the slip. Thus, the amount of R13 791,40 was calculated by summing all the individual deductions: $$ \boxed{8780,74 + 2753,92 + 2131,00 + 16,50 + 109,24 = 13791,40} $$ 2.1.4 Step 1: Identify Mrs. Ngomane's nett salary from the salary advice. Nett salary = R23 827,60 Step 2: Calculate 4,5% of the nett salary. $$ \text{Amount transferred} = 4,5\% \times \text{Nett salary} $$ $$ \text{Amount transferred} = \frac{4,5}{100} \times 23827,60 $$ $$ \text{Amount transferred} = 0,045 \times 23827,60 $$ $$ \text{Amount transferred} = 1072,242 $$ The amount she transfers every month is $\boxed{\text{R1 072,24}}$. 2.1.5 Step 1: Identify Mrs. Ngomane's basic monthly salary from the salary advice. Basic salary = R36 719,00 Step 2: Calculate the annual basic salary by multiplying the monthly basic salary by 12 months. $$ \text{Annual Basic Salary} = \text{Monthly Basic Salary} \times 12 $$ $$ \text{Annual Basic Salary} = 36719,00 \times 12 $$ $$ \text{Annual Basic Salary} = 440628,00 $$ The salary notch amount of R440 628,00 was calculated by multiplying the basic monthly salary by 12 months: $$ \boxed{36719,00 \times 12 = 440628,00} $$
