Calculate the money left over from a given income after a list of expenditures and advise on wise money usage.

$$A = \text{R } 200 + \text{R } 2050 + \text{R } 500 + \text{R } 350 + \text{R } 400 + \text{R } 700 + \text{R } 900 + \text{R } 300 + \text{R } 600 + \text{R } 4500 + \text{R } 317$$ $$A = \text{R } 10817.00$$

$$\text{Income} = \text{R } 15435.20$$ $$B = \text{Income} - A$$ $$B = \text{R } 15435.20 - \text{R } 10817.00$$ $$B = \text{R } 4618.20$$

The values are:

• $A = \boxed{\text{R } 10817.00}$
• $B = \boxed{\text{R } 4618.20}$

Question 1.1.2

Since the value of B is positive ($B = \text{R } 4618.20$), it means the family has money left over after all their expenses. Therefore, the family is using their money wisely.

Question 1.1.3

If the family were not using their money wisely, two pieces of advice to improve their spending could be:

• Create a detailed budget and track all expenses to identify areas where spending can be reduced.
• Reduce discretionary spending on non-essential items like entertainment and clothing, or look for cheaper alternatives for groceries and toiletries.

Question 1.1.4

Occasional expenses are costs that do not occur regularly (e.g., monthly or weekly) but happen from time to time, often unexpectedly or annually. An example of an occasional expense is car maintenance or medical emergencies.
