Clara is taking a medicine for a common cold. Her body metabolizes the medicine over a certain time interval. The table below shows the amount of medicine f(t), in mg, that was present in Clara's body after time t:

Answer 1

t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41


Heidi was administered 300 mg of the same medicine. The amount of medicine in her body f(t) after time t is shown by the equation below:

(t) = 300(0.946)t

Which statement best describes the rate at which Clara’s and Heidi's bodies eliminated the medicine?
Clara's body eliminated the antibiotic faster than Heidi's body.

Clara's body eliminated the antibiotic at the same rate as Heidi's body.
