That's the data you need:

2020-01-01. 258.820

2020-02-01, 259.050

2020-03-01, 257.953

2020-04-01, 255.902

Now comes the calculations.

Remember that the COVID-19 pandemic began around March 2020. With that in mind, lets calculate some price changes for a few months. I do the first calculation to give you the hint.

The CPI for 2019-12-01 was 258.444 and for 2020-01-01 it was 258.820. So the percentage change over one month was 0.1455%. It is customary to multiply monthly percentage changes by 12 to annualize the numbers. So we get 0.1455% * 12 = 1.74583%.

Now, you calculate the annualized percentage price changes for the following months:

1. Annualized percentage price change from 2020-01-01 to 2020-02-01 = ____ percent (Don't include % sign in the answer box)

2. Annualized percentage price change from 2020-02-01 to 2020-03-01 = ___ percent (Don't include % sign in the answer box)

3. Annualized percentage price change from 2020-03-01 to 2020-04-01 = ____ percent (Don't include % sign in the answer box)

By the way, these percentage changes are called inflation rates.
