The CPI or the Customer Price Index is calculated through the equation,

CPI = (price at a certain year / price at the base year) x 100

If our base year is 1983, the price of a year-long newspaper subscription will cost,

193 = (price at a certain year / 12.75) x 100

price at a certain year = $24.6075

Thus, the current price which is $28.50 is slightly higher than the expected price based on the given CPI.
