1.15

Explanation:

The computation of the price in 2005 dollars is shown below:

= Price in 1979 * (CPI in 2005) : (CPI in 1979)

= $0.43 * (100) : (37.4)

= (43) : (37.4)

= 1.1497 or 1.15

Simply we do the proportion based on the CPI in 2005 and Price in 1979 and then divide it by the CPI in 1979. Based on the given information, the price in 2005 dollars is 1.15
