The consumerprice index was 125.

The inflation rate is calculated using the formula:

Inflation Rate=CPIcurrent−CPIpreviousCPIprevious×100\text{Inflation Rate} = \frac{\text{CPI}_{\text{current}} - \text{CPI}_{\text{previous}}}{\text{CPI}_{\text{previous}}} \times 100Inflation Rate=CPIprevious​CPIcurrent​−CPIprevious​​×100

Substitute the given values:

Inflation Rate=125.9−123.0123.0×100=2.9123.0×100≈2.36%\text{Inflation Rate} = \frac{125.9 - 123.0}{123.0} \times 100 = \frac{2.9}{123.0} \times 100 \approx 2.36\%Inflation Rate=123.0125.9−123.0​×100=123.02.9​×100≈2.36%

B. 2.30%: This is close but results from rounding errors or miscalculation.

C. 0.98%andD. 1.02%: These values are far below the correct inflation rate calculated using the formula.
