Question

Examine the following graph for a particular isotope. 
-After 24 days, approximately how much of the sample is left?

Quizplus · Accepted Answer

The question seems to be about a substance undergoing exponential decay, likely with a half-life. Assuming the half-life is 6 days, after 24 days (which is 4 half-lives), the sample would be reduced to 1/16 of its original amount. If the original amount was 20 g, then 20 g / 16 = 1.25 g would remain.
