1.12: Calculating Percentage Increase in Petrol Price

The petrol price has increased from $R 12.50$ to $R 13.10$ per litre. To calculate the percentage increase in the petrol price, we need to find the difference between the new and old prices, divide it by the old price, and then multiply by 100.

Step 1: Find the Difference Between the New and Old Prices

The difference between the new and old prices is $R 13.10 - R 12.50 = R 0.60$ .

Step 2: Divide the Difference by the Old Price

To find the percentage increase, we need to divide the difference by the old price. So, we divide $R 0.60$ by $R 12.50$ .

$R 0.60 ÷ R 12.50 = 0.048$

Step 3: Multiply by 100

To convert the decimal to a percentage, we multiply by 100.

$0.048 × 100 = 4.8\%$

Therefore, the petrol price has increased by 4.8%.

Calculating the Percentage Increase in Data Bundle Prices

To calculate the percentage increase in data bundle prices, we need to find the difference between the new and old prices, divide it by the old price, and then multiply by 100.

Step 1: Find the Difference Between the New and Old Prices

Let's assume that the old price of the data bundle was $R 10$ for 100 MB, and the new price is $R 50$ for 500 MB. The difference between the new and old prices is $R 50 - R 10 = R 40$ .

Step 2: Divide the Difference by the Old Price

To find the percentage increase, we need to divide the difference by the old price. So, we divide $R 40$ by $R 10$ .

$R 40 ÷ R 10 = 4$

Step 3: Multiply by 100

To convert the decimal to a percentage, we multiply by 100.

$4 × 100 = 400\%$

Therefore, the data bundle price has increased by 400%.
