Answer 1

Answer:

$2.82

Explanation:

The CPI is the measure of the average changes in prices of consumer goods and services. The CPI compares current prices and prices at the base year.

CPI is expressed as a percentage. It represents the cost of goods in a given year divided by the cost of goods in the base year multiplied by 100.

In 1970, the movie price was $0.50, and CPI was 38.8%

in 2011, CPI was 218.8%; the movie price will be?

in 1970: $0.50 =38.8%

in 2011: ? = 218.8%

?= 218.8/38.8 x $0.50

?=5.6392 x 0.50

=$2.81896

=$2.82
