Consider a business that sells burgers. The selling price of each burger is R30.00. The fixed costs are R120.00 and the cost to make one burger is R10.00. A) Determine the formula for Income and Expen

• Income (R) = Number of burgers sold $\times$ R$30.00$
• Expense (R) = Fixed costs + (Number of burgers sold $\times$ Cost to make one burger) Expense (R) = R$120.00$ + (Number of burgers sold $\times$ R$10.00$)

So, A = $\boxed{\text{120}}$.

So, B = $\boxed{\text{180}}$.

The completed table is:

2.3.2

• Income (Number of burgers, Income in R): (0, 0), (2, 60), (4, 120), (6, 180), (8, 240), (10, 300)
• Expense (Number of burgers, Expense in R): (0, 120), (2, 140), (4, 160), (6, 180), (8, 200), (10, 220)

Plot the income points and draw a line through them.
Plot the expense points and draw a line through them.
(Note: As an AI, I cannot draw the graph for you, but you can plot these points on graph paper.)

The break-even point is where the Income graph and the Expense graph intersect. At this point, Income equals Expense.
From the table in 2.3.1, when 6 burgers are sold, both Income and Expense are R180.
Therefore, the break-even point is $\boxed{\text{(6 burgers, R180)}}$.
