Assume the half-life of a certain drug is 5 hours and 100 mg of that drug was given as a treatment. (This means that every 5 hours the amount of the drug in the system is cut in half, and at the beginning there were 100mg of the drug in the system.)beginning there were 100mg of the drug in the system.)

table below:

Hours after taking drug

Amount of drug in system

0 0

5 0

10 0

15 0

(imagine a table right here)

What is an equation for the amount of the drug remaining in the system t hours after taking 100 mg.

Using your formula, find out how long it will take before there is less than 1 mg in the body.
