Question

How many cases of 8 dram vials should be ordered to last 2 weeks if there are 500 vials per case and the pharmacy uses 120 vials per day on average?

A) 4 cases
B) 5 cases
C) 6 cases
D) 7 cases

Answer 1

To calculate the number of cases needed for 2 weeks, multiply the daily vial usage by 14 days to get the total vials needed, then divide by the number of vials per case. After calculating, it's clear that 4 cases are needed to last 2 weeks.

Step-by-step explanation:

The subject of this question is mathematics, and the question concerns calculating the amount of cases needed based on a given daily usage rate. To solve this, we first calculate the total number of vials needed for 2 weeks by multiplying the average daily usage of 120 vials by 14 days (2 weeks). This gives us a total need of 1,680 vials. We then divide that number by the number of vials per case, which is 500 vials, to determine how many cases are needed.

The calculation will look like this:

1. Calculate total vial usage: 120 vials/day × 14 days = 1,680 vials.
2. Divide total vials needed by vials per case: 1,680 vials ÷ 500 vials/case = 3.36 cases.
3. Since you cannot order a fraction of a case, you would need to round up to the next whole number. Therefore, the pharmacy would need to order 4 cases.

So, the correct answer is A) 4 cases.
