Determine the equation that Mr. Kheswa will use to calculate his total monthly costs.

From the previous context (15.1.3), the total monthly fixed costs are R8 500.
The variable cost per goat is R1 000 (as stated in the problem's context, typically from TABLE 1).

Let $n$ represent the number of goats.

15.1.5
The value A is not visible in the provided image. Assuming A refers to the total monthly cost for 10 goats (a common value in such tables):

15.2.1
Break-even in this context refers to the point where Mr. Kheswa's total monthly income from selling goats is exactly equal to his total monthly costs. At this point, he makes zero profit and incurs zero loss.

15.2.2
The formula for income is given as: $\text{Income} = 1800 \times n$, where $n$ is the number of goats sold.

For B, the number of goats sold ($n$) is 6.

For C, the total monthly income is R54 000.

15.2.3
We need to calculate the profit for 9 goats (normal cost) and 14 goats (reduced cost) and then verify the claim.
Assumption: The problem does not specify the "reduced cost price" when buying in bulk. We will assume a 10% reduction from the normal cost price of R1 000 per goat, making the reduced cost price R900 per goat.

Normal cost price per goat = R1 000.
Total monthly fixed costs = R8 500.
Income for 9 goats = $1800 \times 9 = \text{R}16\,200$.
Cost for 9 goats = $8500 + (1000 \times 9) = 8500 + 9000 = \text{R}17\,500$.
Profit for 9 goats = Income - Cost = $16\,200 - 17\,500 = -\text{R}1\,300$. (This indicates a loss).

Reduced cost price per goat = R900 (based on assumption).
Income for 14 goats = $1800 \times 14 = \text{R}25\,200$.
Cost for 14 goats = $8500 + (900 \times 14) = 8500 + 12600 = \text{R}21\,100$.
Profit for 14 goats = Income - Cost = $25\,200 - 21\,100 = \text{R}4\,100$.

Is Profit (9 goats) = 6.9% of Profit (14 goats)?
The claim states: Profit (9 goats) = $0.069 \times$ Profit (14 goats).
Substitute the calculated profits:
$-1\,300 = 0.069 \times 4\,100$
$-1\,300 = 282.9$
Since $-1\,300 \neq 282.9$, the claim is incorrect.
The claim is $\boxed{\text{Incorrect}}$.

15.2.4
To draw the graph for the monthly income, you would plot the points from TABLE 2 on the same answer sheet where the monthly cost graph is provided.
The points to plot for monthly income (Number of goats sold, Total monthly Income) are:

• $(0, 0)$
• $(2, 3600)$
• $(4, 7200)$
• $(6, 10800)$ (using value B from 15.2.2)
• $(8, 14400)$
• $(10, 18000)$
• $(20, 36000)$
• $(30, 54000)$ (using value C from 15.2.2) Connect these points with a straight line, starting from $(0,0)$, as the income increases linearly with the number of goats sold.

15.2.5
The break-even point occurs when Total monthly cost = Total monthly income.

Total monthly cost: $8500 + 1000n$
Total monthly income: $1800n$

Since you cannot sell a fraction of a goat, the break-even point is reached when selling the
