Answer :

Final Answer:

The 2000 price of a taco in 1970 dollars is $0.29 (B).

Explanation:

To calculate the 2000 price of a taco in 1970 dollars, we need to adjust the 2000 price for inflation using the Consumer Price Index (CPI). The formula for this adjustment is:

Adjusted Price = (Current Price / Current CPI) * Base Year CPI

In this case, the current price in 2000 is $1.09, the current CPI in 2000 is 172.2, and the base year CPI in 1970 is 38.8. Plugging these values into the formula:

Adjusted Price = ($1.09 / 172.2) * 38.8 = $0.245

So, the 2000 price of a taco in 1970 dollars is approximately $0.25.

However, none of the provided answer choices match this result. The closest option is $0.29 (B), which is the price of a taco in 1970 dollars rounded to the nearest cent. Therefore, the correct answer is $0.29 (B).
