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
Let the number be x. The other number is also x.
Given the first number is 24.6 and sum is -44.85
24.6 + x + x = -44.85
Combine like terms:
2x + 24.6 = -44.85
Add 24.6 on both sides:
2x = -44.85 - 24.6
Evaluate Right Hand Side:
2x = -69.45
Divide both sides by 2:
x =- 34.725
Answer: The two numbers are both -34.725.
