Answer 2

Calculating the Number of Medication Packs Needed

To calculate the number of medication packs needed for the entire course of treatment, we can use the following information:

- The medication needs to be taken at a dosage of 0.5 g three times a day for 14 days. - Each pack contains 20 tablets of the medication, with each tablet being 0.5 g.

Calculation

To find out how many packs are needed for the entire course of treatment, we can calculate the total number of tablets required for 14 days and then determine the number of packs needed to obtain that quantity.

The total number of tablets required for 14 days can be calculated as follows: - 0.5 g three times a day for 14 days = 0.5 g * 3 * 14 = 21 g for the entire course of treatment.

Since each tablet is 0.5 g, the total number of tablets required for the entire course of treatment is: - 21 g / 0.5 g per tablet = 42 tablets for the entire course of treatment.

Given that each pack contains 20 tablets, the number of packs needed can be calculated as: - 42 tablets / 20 tablets per pack = 2.1 packs.

Conclusion

To ensure the patient has enough medication for the entire course of treatment, at least 3 packs of the medication will be needed.
