Answer:
So after the second tablet there is 360-mg of drug in the body.
So after the third tablet there is 372-mg of drug in the body.
Step-by-step explanation:
We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.
We know that 20%=0.2.
We conclude that after the first pill, 300mg of the drug is in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:
So after the second tablet there is 360-mg of drug in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:
So after the third tablet there is 372-mg of drug in the body.
