<u>Answer:</u>
CPI in year 2 = 108.78$
Rate of inflation from 1st year to 2nd = 0.9%
<u>Explanation:</u>
CPI = Consumer Price Index
= (Cost of Market Basket in Given year/Cost of Market Basket at base) * 100
given price of bread and a gallon of milk
in year one (base year) = $1.50 and $2.90 respectively and that
in second year = $1.65 and $3.10 respectively
Since the basket consists of 3 loaves of bread and 1 gallon of milk
Cost of basket in 2nd year = 3 x 1.65 + 1 x 3.10 = 8.05
cost of basket in 1st year = 3 x 1.50 + 1 x 2.90 = 7.40
CPI = (8.05/7.40) x 100
= 108.78 $
we know ,Rate of inflation is given by
= (CPI in year 2 - cpi in year 1)/ cpi in year 1
= (108.78 -100)/100
= 0.0878
= 0.9%
