A clinic's inventory shows 350 boxes of sterile gloves. Each box contains 100 pairs of gloves. If the clinic uses an average of 700 pairs of gloves per day, how many days will the current inventory last?
- A35 days
- B25 days
- C50 days
- D70 days
Show answer & explanationAnswer & explanation
Correct answer: C. 50 days
First, calculate the total number of glove pairs: 350 boxes * 100 pairs/box = 35,000 pairs. Then, divide the total pairs by the daily usage: 35,000 pairs / 700 pairs/day = 50 days.
Why the other options are wrong
- A. This answer could be a miscalculation, perhaps dividing 350 by 10 without proper unit handling.
- B. This answer might result from a miscalculation, such as dividing 350 by 700 and then multiplying by 50.
- D. This answer suggests an error in the initial calculation of total pairs or the division.
Inventory Duration Calculation
Determining how long a current supply of an item will last based on its total quantity and average daily consumption.
- Requires total quantity of the item in consistent units.
- Requires the average consumption rate per day.
- Formula: Total Quantity / Daily Consumption Rate = Duration in Days.
Memory trick: Total Items, Divided by Daily Use, tells you when you're through.
