6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>The decay equation for the 13 grams of iron-52 is:
Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:
So 6.665 grams of the 13 grams remain after 8 hours.

Given:
The inequality is:
To find:
The solution of the given inequality.
Solution:
We have,
Multiply both sides by 3.
Divide both sides by -8 and change the sign of inequality.
It can be written as:
Therefore, the correct option is A.
