Answer
Explanation:
Step1: Recall inflation - adjustment formula
The formula to adjust a price from an earlier year to a later - year (constant dollars) is $P_{adjusted}=P_{original}(1 + r)$, where $P_{original}$ is the price in the earlier year and $r$ is the inflation rate for the time - span between the earlier year and the later year.
Step2: Identify values for 1980 to 2020
For the price of gold in 1980, $P_{original}=568.97$ and the inflation rate $r = 2.14$ (since 214% = 2.14).
Step3: Calculate the adjusted price
$P_{adjusted}=568.97\times(1 + 2.14)$ $P_{adjusted}=568.97\times3.14$ $P_{adjusted}=1786.5658\approx1786.57$
Answer:
$1786.57$
