The price of petrol is increased from R12.58 per litre to R13.28 per litre. Determine the percentage increase in the price.

To determine the percentage increase in the price of petrol, we can use the formula: \[ \text{Percentage Increase} = \left( \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \right) \times 100\% \] Given: - Old Price = R12.58 per litre - New Price = R13.28 per litre Substitute the values into the formula to find the percentage increase in the price of petrol. Calculate the value by following steps: - step0: Calculate: \(\frac{\left(13.28-12.58\right)}{12.58}\times 100\) - step1: Remove the parentheses: \(\frac{13.28-12.58}{12.58}\times 100\) - step2: Subtract the numbers: \(\frac{0.7}{12.58}\times 100\) - step3: Divide the terms: \(\frac{35}{629}\times 100\) - step4: Multiply: \(\frac{35\times 100}{629}\) - step5: Multiply: \(\frac{3500}{629}\) The percentage increase in the price of petrol is approximately 5.56%.
