If i currently have 12 bottles of water on my shelf, and want to keep a minimum level of 6 bottles at all times. I have an average sale 2 per day. What is the minimum number i would order for enough bottles for 7 days?

thanks.

On the average, there are enough bottles for (12-6)/2=three more days. For seven days, we need 2*(7-3)=eight more bottles.

8 more bottles

To calculate the minimum number of bottles you would need to order for enough bottles for 7 days, you need to consider the average sales per day and the minimum level you want to maintain.

1. Calculate the number of bottles you would need to fulfill the average sales per day for 7 days.
- Average sales per day: 2 bottles
- Total bottles sold in 7 days: 2 bottles/day * 7 days = 14 bottles

2. Calculate the number of bottles you need to maintain the minimum level of 6 bottles at all times.
- Minimum level of bottles: 6 bottles

3. Add the bottles needed to fulfill the average sales and the minimum level.
- Total bottles needed: 14 bottles (average sales per day for 7 days) + 6 bottles (minimum level) = 20 bottles

Therefore, the minimum number of bottles you would need to order for enough bottles for 7 days is 20 bottles.

To calculate the minimum number of bottles you need to order for enough bottles for 7 days, we need to consider the average sales per day, the number of bottles you already have, and the minimum level you want to maintain.

First, let's calculate the total sales for 7 days. Since you sell an average of 2 bottles per day, multiplying this by 7 gives us 2 x 7 = 14 bottles sold in total during this period.

Next, we need to determine the minimum level you want to maintain, which is 6 bottles. So, subtracting 6 from the total sales for 7 days, we have 14 - 6 = 8 bottles that you need to order to replenish your stock.

However, you also have 12 bottles already on your shelf. Since you want to keep a minimum level of 6 bottles at all times, the number of bottles you need to order changes based on your current stock. If your current stock exceeds the minimum level, you don't need to order any bottles.

In this case, you have 12 bottles already, which is more than the minimum level of 6. So, you do not need to order any bottles since your stock is sufficient for the next 7 days.

To summarize, you do not need to order any bottles as you already have more than the minimum level of 6 bottles on your shelf.
