Answer:
18.75 mg
Step-by-step explanation:
We can model this problem using the exponencial equation:
y = yo * (1 + r)^x
Where y is the final value, yo is the inicial value, r is the rate and x is the amount of time.
In this problem, we want to find y after x = 4 hours (from 9am to 1pm), we have yo = 300 and r = -0.5 (for every hour, half the caffeine leaves the body). So we have that:
y = 300 * (1 - 0.5)^4
y = 300 * 0.5^4
y = 300 * 0.0625
y = 18.75 mg
