-An accidental spill of 75 grams of radioactive material in a local stream has led to the presence of radioactive debris decaying at a rate of $3 \%$ each day. Find how much debris still remains after 8 days.
A) $54 \mathrm {~g}$
B) $4 \mathrm {~g}$
C) $64 \mathrm {~g}$
D) $59 \mathrm {~g}$

Quizplus · Accepted Answer

The amount of debris remaining after 8 days can be calculated using the formula for exponential decay: $ A = P(1 - r)^t $, where $ P = 75 $ grams, $ r = 0.03 $, and $ t = 8 $. This gives $ A = 75(0.97)^8 \approx 58.7 $ grams, which rounds to 59 grams.
