The formula to calculate the rate of inflation between two years is:

$\text{Inflation Rate} = \left( \frac{\text{CPI in Final Year} - \text{CPI in Initial Year}}{\text{CPI in Initial Year}} \right) \times 100$

Using the given values:

• CPI in 2005 (Final Year) = 190.7
• CPI in 1995 (Initial Year) = 150.3

Substituting into the formula:

$\text{Inflation Rate} = \left( \frac{190.7 - 150.3}{150.3} \right) \times 100$

Let's calculate that.The rate of inflation from 1995 to 2005 is approximately 26.88%.

Tip: When calculating inflation over multiple years, it’s important to adjust for compounding effects if you’re measuring year-by-year inflation rates.
