Analyze the provided monthly budget for the Welden family and calculate the total income, total expenses, and total amount left over.

Add Mr Welden's income, Mrs Welden's income, and the tuck shop profit.

$$\text{Total Income} = \text{R}5600 + \text{R}4800 + \text{R}2200$$ $$\text{Total Income} = \text{R}12600$$

The "Total Income" in the table is R12 600, which is ✅ Correct.

Sum all the fixed expenses listed.

$$\text{Fixed Expenses} = \text{R}2000 (\text{Rent}) + \text{R}1500 (\text{Car Repayment}) + \text{R}400 (\text{School Fees}) + \text{R}380 (\text{Car Insurance}) + \text{R}1200 (\text{Medical Aid}) + \text{R}660 (\text{Insurance Policy}) + \text{R}150 (\text{Savings}) + \text{R}399 (\text{Television subscription})$$ $$\text{Fixed Expenses} = \text{R}6689$$

Sum all the variable expenses listed.

$$\text{Variable Expenses} = \text{R}2300 (\text{Food}) + \text{R}470 (\text{Municipality bill}) + \text{R}140 (\text{House maintenance}) + \text{R}650 (\text{Petrol}) + \text{R}780 (\text{Cell phone contract}) + \text{R}300 (\text{Clothing account}) + \text{R}110 (\text{Bank chargers}) + \text{R}110 (\text{Entertainment}) + \text{R}200 (\text{Other Bills})$$ $$\text{Variable Expenses} = \text{R}5060$$

Add the total fixed expenses and total variable expenses.

$$\text{Total Expenses} = \text{Fixed Expenses} + \text{Variable Expenses}$$ $$\text{Total Expenses} = \text{R}6689 + \text{R}5060$$ $$\text{Total Expenses} = \text{R}11749$$

The "Total Expenses" in the table is R12 439, which is ❌ Incorrect. The correct total expenses should be R11 749.

Subtract the total expenses from the total income.

$$\text{Total left over} = \text{Total Income} - \text{Total Expenses}$$ $$\text{Total left over} = \text{R}12600 - \text{R}11749$$ $$\text{Total left over} = \text{R}851$$

The "Total left over" in the table is R161, which is ❌ Incorrect based on the correct total expenses.

The correct calculations are:

• Total Income: $\boxed{\text{R}12600}$
• Total Expenses: $\boxed{\text{R}11749}$
• Total left over: $\boxed{\text{R}851}$
