Answer: $141.78
Step-by-step explanation:
The Consumer Price Index(CPI) is useful for calculating inflation because it monitors the change in certain goods and services over the years.
It can be used in the following manner.
Price in 2018 = (Price in 2001 /CPI in 2001)* CPI in 2018 year
= (100 / 177.1) * 251.1
= $141.78
