Mrs Mkize works at a construction company as an engineer. She earns a monthly salary of R37 500. Below is the Income and Expenditure statement for the Mkize household.

Here are the solutions to Question 2 based on the provided Income and Expenditure statement. 2.1 • One fixed expense: Rent (or Car instalment) • One variable expense: Groceries (or Social events, Electricity & water, Cellphone airtime) 2.2 Step 1: Identify Mrs Mkize's monthly income. Mrs Mkize's monthly income is R37 500. Step 2: Calculate 17% of her monthly income for medical aid. A = 17\% × R37\,500 A = 0.17 × R37\,500 A = R6\,375 The value of A, her monthly contribution to medical aid, is R6 375. 2.3 Step 1: List all expenditure items and their values, including the calculated value of A. • Rent: R8 500 • Groceries: R6 500 • Medical aid (A): R6 375 (from 2.2) • Social events: R3 750 • Electricity & water: R6 250 • Car instalment: R4 600 • Cellphone airtime: R800 Step 2: Sum all the expenditure items to find B, the total expenditure. B = R8\,500 + R6\,500 + R6\,375 + R3\,750 + R6\,250 + R4\,600 + R800 B = R36\,775 The value of B, the total expenditure, is R36 775. 2.4 Step 1: Calculate the monthly money left over. Money left over = Total Income - Total Expenditure (B) Money left over = R37\,500 - R36\,775 Money left over = R725 Step 2: Calculate the total savings after 10 months. Total Savings = Monthly money left over × 10 Total Savings = R725 × 10 Total Savings = R7\,250 Step 3: Compare the total savings with the laptop cost. Laptop cost = R11 999 Total Savings = R7 250 Since R7 250 is less than R11 999, Mrs Mkize will not have enough money to buy the laptop after 10 months. No, Mrs Mkize will not have enough money. 2.5 Step 1: Calculate the new amount spent on groceries. New Groceries = Original Groceries × (1 + Percentage Increase) New Groceries = R6\,500 × (1 + 0.12) New Groceries = R6\,500 × 1.12 New Groceries = R7\,280 Step 2: Calculate the new total expenditure. New Total Expenditure = B - Original Groceries + New Groceries New Total Expenditure = R36\,775 - R6\,500 + R7\,280 New Total Expenditure = R37\,555 Step 3: Determine the new money left over (profit or deficit). Money left over = Total Income - New Total Expenditure Money left over = R37\,500 - R37\,555 Money left over = -R55 The increase in grocery prices will result in a deficit of R55 at the end of the month. 2.6 One way the Mkize family can save more money for the month is by reducing spending on social events.
