im not very sure but i think its A or C
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
Negative 5
means put a point 5 units to the left of 0
C is answer
80% × x = 32
.80x = 32
x = 32/.8
x = 40
