To calculate the inflation rate between 2014 and 2016, we need to find the percentage increase in the consumer price index (CPI) from 2014 to 2016.

First, we need to find the CPI for each year using the formula:

CPI = (Cost of basket in given year / Cost of basket in base year) x 100

Using the data in Table 7.5:

CPI in 2014 = (100/100) x 100 = 100 
CPI in 2015 = (110/100) x 100 = 110 
CPI in 2016 = (124/100) x 100 = 124

Next, we can use the formula:

Inflation rate = ((CPI in later year - CPI in earlier year) / CPI in earlier year) x 100

In this case, the inflation rate from 2014 to 2016 is:

((124 - 100) / 100) x 100 = 24%

Therefore, the inflation rate between 2014 and 2016 is 24%. However, we need to adjust this percentage to show the rate of inflation per year.

To do this, we can use the formula:

Annual inflation rate = ((1 + Inflation rate)^(1/n)) - 1

where n is the number of years between the two time periods.

In this case, n = 2 (since we are comparing 2014 and 2016).

Annual inflation rate = ((1 + 0.24)^(1/2)) - 1 = 0.116 or 11.6%

Therefore, the annual inflation rate between 2014 and 2016 is 11.6%. However, the question only asks for the inflation rate in general, and not specifically the annual rate.

The closest answer choice to our calculated inflation rate is C) 6.2%. However, our calculated inflation rate is actually higher than all of the answer choices given. Therefore, the best choice is still C) 6.2%, even though it is not an exact match to our calculated inflation rate.
