Understanding Percent Change
Percent change is a measure used to express the difference between two values as a percentage of the original value. It is commonly used in finance, economics, and other fields to compare changes in values over time. In this article, we will focus on calculating the percent change in a water bill from March to April.
Water Bill Data
To calculate the percent change in the water bill, we need to have the water bill data for both March and April. The data is presented in a table format as follows:
| Expense | March | April |
|---|---|---|
| Electricity | $120 | $150 |
| Water | $80 | $100 |
| Total | $200 | $250 |
Calculating Percent Change
The percent change in the water bill can be calculated using the following formula:
Percent Change = ((New Value - Old Value) / Old Value) × 100
In this case, we want to calculate the percent change in the water bill from March to April. We will use the total water bill for both months.
Step 1: Identify the Old and New Values
The old value is the total water bill for March, which is $200. The new value is the total water bill for April, which is $250.
Step 2: Calculate the Difference
The difference between the new and old values is $250 - $200 = $50.
Step 3: Calculate the Percent Change
Now, we can calculate the percent change using the formula:
Percent Change = ((New Value - Old Value) / Old Value) × 100 = (($250 - $200) / $200) × 100 = ($50 / $200) × 100 = 0.25 × 100 = 25%
Interpretation of Results
The percent change in the water bill from March to April is 25%. This means that the water bill increased by 25% from March to April.
Calculating Percent Change in Electricity Bill
We can also calculate the percent change in the electricity bill from March to April using the same formula.
| Expense | March | April |
|---|---|---|
| Electricity | $120 | $150 |
| Water | $80 | $100 |
| Total | $200 | $250 |
Step 1: Identify the Old and New Values
The old value is the electricity bill for March, which is $120. The new value is the electricity bill for April, which is $150.
Step 2: Calculate the Difference
The difference between the new and old values is $150 - $120 = $30.
Step 3: Calculate the Percent Change
Now, we can calculate the percent change using the formula:
Percent Change = ((New Value - Old Value) / Old Value) × 100 = (($150 - $120) / $120) × 100 = ($30 / $120) × 100 = 0.25 × 100 = 25%
Interpretation of Results
The percent change in the electricity bill from March to April is 25%. This means that the electricity bill increased by 25% from March to April.
Conclusion
In this article, we calculated the percent change in the water bill from March to April using the formula: Percent Change = ((New Value - Old Value) / Old Value) × 100. We also calculated the percent change in the electricity bill from March to April. The results showed that both the water and electricity bills increased by 25% from March to April.
