Nancy is taking inventory in the pharmacy to make sure there is enough eye medication in the pharmacy. She counts 10 boxes of travoprost and the pharmacy needs 15 boxes to maintain a minimal level in stock. Nancy counts 3 boxes of latanoprost and the pharmacy needs to 12 boxes. Calculate how many boxes of each Nancy needs to order.

Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy.

Step-by-step explanation:

Nancy counts 10 boxes of travoprost and the pharmacy needs 15 boxes to maintain a minimal level in the stock.

So, there is a need to order (15 - 10) = 5 boxes of travoprost.

Again, Nancy counts 3 boxes of latanoprost and the pharmacy needs to 12 boxes.

So, there is a need to order (12 - 3) = 9 boxes of latanoprost.

Therefore, Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy. (Answer)
