Answer:
1.97 ounces
Step-by-step explanation:
-The exponential decay function is given by the formula:
Given that the half-life is 4 days, we can substitute in the formula to solve the rate of decay for a single half-life:
#Since, 1 week has 7 days, 3 weeks is a 21-day period, thus, t=21.
#We substitute and solve for the amount remaining after 21days of decay:
Hence, the amount remaining after 3 weeks of decays is approximately 1.97 ounces
