Sure, let's go through each question step-by-step.
### 1.1.1 Briefly explain the difference between fixed and variable expenses.
Fixed Expenses are costs that do not change from month to month. These expenses are usually contractual and have to be paid regularly, and their amounts are generally the same each month. Examples include rent, car insurance, cell phone contracts, medical aid, and school fees.
Variable Expenses are costs that can fluctuate from month to month based on consumption or usage. These expenses can vary widely. Examples include water and electricity, groceries, and entertainment.
### 1.1.2 Determine the value of [tex]\(A\)[/tex], the total monthly income.
The total monthly income [tex]\(A\)[/tex] is calculated by summing up all the income sources. According to the problem, Celina's salary is not provided (or is zero), and Zane's salary is R12,000.
So, the total monthly income [tex]\(\mathbf{A}\)[/tex] is:
[tex]\[ \text{Total Income} = \text{Celina's Salary} + \text{Zane's Salary} = 0 + R12,000 = R12,000 \][/tex]
### 1.1.3 List TWO variable expenses.
Two examples of variable expenses provided from the table are:
1. Water and electricity: [tex]\(R14,300\)[/tex]
2. Groceries: [tex]\(R5,200\)[/tex]
### 1.1.4 How much does the family pay for the school children for the month?
The amount paid for the school fees for the two children for the month is [tex]\(R2,400\)[/tex].
By summarizing each answer:
1. Fixed expenses refer to costs that remain constant each month, while variable expenses are costs that can change depending on usage or consumption.
2. The total monthly income [tex]\(A\)[/tex] is [tex]\(R12,000\)[/tex].
3. Two variable expenses include:
- Water and electricity: [tex]\(R14,300\)[/tex]
- Groceries: [tex]\(R5,200\)[/tex]
4. The family pays [tex]\(R2,400\)[/tex] for the school fees for both children for the month.
Hope this helps!
