Answer:
7.5
Step-by-step explanation:
Data provided
CPI in the year 2010 = 180.60
CPI in the year 2009 = 168.00
The computation of rate of inflation is shown below:
Inflation rate =((CPI in the year 2010 - CPI in the year 2009) ÷ CPI in the year 2009) × 100
= (180.60 - 168.00) ÷ 168.00 × 100
= 12.6 ÷ 168.00 × 100
= 0.075 × 100
= 7.5
Therefore for computing the inflation rate we simply applied the above formula.
