When a certain over the counter drug enters the bloodstream, it gradually dilutes, decreasing exponentially. you take a 200 mg dose at 8: 00pm, and by 11: 00pm, there is only 75 mg remaining.

a) if the drug is only effective with at least 65 mg in the blood stream, about what time should you take another dose?

b) assume you don’t take another dose after 8: 00pm, how much would be left in your blood stream after 10 days?

a) If the drug is only effective with at least 65 mg in the blood stream, about what time should you take another dose?

Step-by-step explanation:am i right

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
