D) 4.5%
To calculate the inflation rate, you can use the following formula:
Inflation rate = ((CPI in year 2 - CPI in year 1) / CPI in year 1) x 100
Using the given numbers, we get:
Inflation rate = ((110 - 105) / 105) x 100
Inflation rate = (5 / 105) x 100
Inflation rate = 0.0476 or 4.76%
Rounding to one decimal place gives us an answer of 4.5%, which is closest to choice D.
if the consumer price index is 105 and your one and 110 in year two what is the inflation from year one to year two?
A) .05%
