Lets do the working for the amount of medication remaining in Noelle's body.
Day 1:
600 × 0.6 = 360
Day 3:
360 × 0.6 = 216
Day 4:
216 × 0.6 = 129.6
Day 5:
129.6 × 0.6 = 77.76
By the time Karey is taking the medication, Noelle only has 77.76 in her body.
This expressed as a percentage in relation to Karey's amount is :
77.76/600 × 100 = 12.96%
= 12.9%

Answer:
we need the table!
Step-by-step explanation:
Answer: she would catch up with Tom in 1 hour.
Step-by-step explanation:
Let t represent the time it will take for Mary to catch up with Tom.
Tom leaves his boat from a dock and travels at a rate of 25 miles per hour.
Distance = speed × time
Distance travelled by Tom in t hours is
25 × t = 25t
Ten minutes later, Mary leaves the same dock in her speedboat and heads after Tom. Converting 10 minutes to hours, it becomes 10/60 hour
Time spent by Mary is (t - 10/60) hours. If she travels at a rate of 30 miles per hour, it means that the distance that she would travel in
(t - 10/60) hours is
30(t - 10/60)
= 30t - 5
By the time she catches up with Tom, they would have covered the same distance. It means that
25t = 30t - 5
30t - 25t = 5
5t = 5
t = 5/5 = 1 hour
