The price of bread has increased from R12 to R18
Calculate the percentage
increase in the price of bread.
The formula to calculate percentage increase is:
percentage increase = (new value - old value) / old value x 100
Applying this formula to the given values:
percentage increase = (18 - 12) / 12 x 100
percentage increase = 6 / 12 x 100
percentage increase = 0.5 x 100
percentage increase = 50%
Therefore, the percentage increase in the price of bread is 50%.
To calculate the percentage increase, you can use the following formula:
Percentage Increase = (New Value - Old Value) / Old Value * 100
In this case, the old value is R12 and the new value is R18:
Percentage Increase = (18 - 12) / 12 * 100
Let's calculate it step-by-step:
Step 1: Calculate the difference between the new and old values
Difference = 18 - 12 = 6
Step 2: Get the ratio of the difference to the old value
Ratio = Difference / Old value = 6 / 12 = 0.5
Step 3: Multiply the ratio by 100 to get the percentage
Percentage Increase = Ratio * 100 = 0.5 * 100 = 50
Therefore, the percentage increase in the price of bread is 50%.
