Write down a formula to represent Lindiwe's total expenses: Total Expenses = Redraw and complete the table to represent Lindiwe's expenses if she sells 0, 50, 100, 150, 200 and 250 tortillas.

• Total Income ($I$): $I = 15n$ Data points: $(0, 0), (50, 750), (100, 1500), (150, 2250), (200, 3000), (250, 3750)$
• Total Expenses (Cost, $C$): $C = 5n + 500$ Data points: $(0, 500), (50, 750), (100, 1000), (150, 1250), (200, 1500), (250, 1750)$

• Draw a horizontal axis (x-axis) and label it "Number of Tortillas (n)".
• Draw a vertical axis (y-axis) and label it "Amount (R)".

• For the x-axis (Number of Tortillas), mark increments of 50 (e.g., 0, 50, 100, 150, 200, 250).
• For the y-axis (Amount in Rands), mark increments of 500 or 750. Ensure the scale goes high enough to include the maximum income (R3750). For example, you could use 0, 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000.

• Plot each of the Total Income data points: $(0, 0), (50, 750), (100, 1500), (150, 2250), (200, 3000), (250, 3750)$.
• Draw a straight line connecting these points. This line should start from the origin $(0,0)$.
• Label this line "Total Income".

• Plot each of the Total Expenses data points: $(0, 500), (50, 750), (100, 1000), (150, 1250), (200, 1500), (250, 1750)$.
• Draw a straight line connecting these points. This line should start from $(0, 500)$ (representing the fixed cost).
• Label this line "Total Expenses".

• The point where the "Total Income" line intersects the "Total Expenses" line is the break-even point.
• From our previous calculation, this point is at (50 tortillas, R750). Mark this intersection point on your graph and label it "Break-even point".

The graph will visually show that below 50 tortillas, expenses are higher than income (loss), and above 50 tortillas, income is higher than expenses (profit).
