Since the comic book is expected to double in value every 5 years, we can divide the 12-year period by 5 to find the number of doubling periods.
12 years ÷ 5 years = 2.4 doubling periods
Since we cannot have a fraction of a doubling period, we round down to the nearest whole number, which means there will be 2 doubling periods in the 12-year time frame.
Now, we need to calculate the final value of the comic book after 2 doubling periods.
Starting with the initial value of $35, we can calculate the value after the first doubling period by multiplying it by 2:
$35 × 2 = $70
Next, we calculate the value after the second doubling period by again multiplying it by 2:
$70 × 2 = $140
Therefore, the value of the comic 12 years from now is $140.
