How many days' worth of medication can a patient take if they have 180 tablets and the prescription is for 2 tablets a day?

To determine how many days' worth of medication a patient has, you start by taking the total number of tablets the patient has and divide that by the number of tablets they are prescribed to take each day.

In this case, the patient has 180 tablets and the prescription is for 2 tablets a day. To find the number of days the medication will last, divide 180 by 2:

180 tablets ÷ 2 tablets/day = 90 days.

This calculation shows that the patient can take their medication for a total of 90 days. This aligns with the correct answer, as it accurately reflects the amount of medication available relative to the prescribed dosage.
