Answer:

99.035%

Explanation:

Data provided in the question:

CPI in 1979 = 72.6

CPI in 1993 = 144.5

Now,

The percentage by which prices rise during the period 1979-1999 will be calculated as :

= [ (CPI in 1993 - CPI in 1979 ) ÷ CPI in 1979 ] × 100%

or

= [ (144.5 - 72.6 ) ÷ 72.6 ] × 100%

or

= [ 71.9 ÷ 72.6 ] × 100%

or

= 99.035%

The percentage by which prices rise during the period 1979-1999 is 99.035%
