They're not right
To find the percentage of Mary's monthly salary that she spends on food, you can follow these steps:
Step 1: Calculate the amount of money Mary spends on food as a percentage of her monthly salary.
Percentage = (Amount spent on food / Monthly salary) × 100
Let's plug in the values we have:
Amount spent on food = R2,800
Monthly salary = R12,000
Percentage = (2,800 / 12,000) × 100
Percentage = 0.2333 × 100
Percentage = 23.33%
Therefore, Mary spends approximately 23.33% of her monthly salary on food.
