Instructions: Round your CPI answer to 3 decimal places and Rate of inflation to 1 decimal place.
Computation of CPI in the subsequent year and the rate of inflation between the base year and the subsequent year:
Cost of CPI Basket of Commodities in the Base Year = 10 * Price of pizzas + Apartment rent + Gasoline and car maintenance charges + Phone service charges
= 10 * $12 + $750 + $150 + $50
= $1,070
Cost of CPI Basket of Commodities in the Subsequent Year = 10 pizzas * Price of pizzas + Apartment rent + Gasoline and car maintenance charges + Phone service charges
= 10 * $15 + $810 + $170 + $40
= $1,170
CPI in the base year = 100
a. CPI in the Subsequent Year = Cost of CPI basket of commodities in the subsequent year/Cost of CPI basket of commodities in the base year
= ($1,170/$1,070) * 100
= 109.346
Rate of Inflation between the Base Year and the Subsequent Year = [(CPI in subsequent year - CPi in base year)/CPI in base year] * 100
= [(109.346-100)/100] * 100
= 9.3%
