Answer:
61.68 mg
Step-by-step explanation:
Given the table :
5:00pm - 400mg
6:00pm - 350mg
7:00pm - 306.25mg
First we obtain the percentage rate at which the drug leaves her system per hour :
Take between 5-6 pm
((400 - 350) / 400) * 100%
(50 / 400) * 100%
0.125 * 100%
= 12.5%
.we can use the exponential function :
A = P(1 - r)^t
r = rate, t = time (hours) ; P= initial amount ; A = final amount
Mg of medicine left when she wakes up at 7:00 am
t = 7:00am - 5:00 pm = 14 hours
P = 400 mg
r = 0.125
A = 400(1 - 0.125)^14
A = 400 * 0.1542100
A = 61.68402913
About 61.68 mg
