### Calculating Inflation Rates for Each Period

The table below shows the index numbers for the cost of a basket of goods and services in each period. Use this information to calculate the inflation rate for each period. Round to two decimal places.

| Period   | Index Number | Inflation Rate   |
|----------|--------------|------------------|
| Period 1 | 112          | -                |
| Period 2 | 120          |                  |
| Period 3 | 124          |                  |
| Period 4 | 130          |                  |

Provide your answer below:

Period 2 = [   ]%; Period 3 = [   ]%; Period 4 = [   ]%

---

### Instructions:

1. The **Index Number** represents the price index for each period.
2. To calculate the **Inflation Rate** for a given period, use the formula:

\[
\text{Inflation Rate} = \left( \frac{\text{Index Number in Current Period} - \text{Index Number in Previous Period}}{\text{Index Number in Previous Period}} \right) \times 100
\]

3. **Period 1** does not have an inflation rate provided as it is the base period.
4. Calculate the inflation rate for **Period 2**, **Period 3**, and **Period 4** and fill in the answers in the provided boxes.

### Example Calculation:

For **Period 2** calculation:

\[
\text{Inflation Rate for Period 2} = \left( \frac{120 - 112}{112} \right) \times 100 \approx 7.14\%
\]

Make sure to apply the same formula to calculate the inflation rates for Period 3 and Period 4. Once calculated, insert the results into the spaces provided.
