Calculation of the Number of Cookie Boxes Sold

To calculate the number of cookie boxes sold before and after lunch, we need to use the given information.

According to the information provided, a total of 9 identical boxes of cookies were sold in the store. Before lunch, 162 kg of cookies were sold, and after lunch, 81 kg were sold.

To find the number of cookie boxes sold before lunch, we need to determine how many kilograms of cookies are in each box.

Let's assume that each box contains the same amount of cookies.

To find the number of boxes sold before lunch, we divide the total weight of cookies sold before lunch (162 kg) by the weight of cookies in each box.

Similarly, to find the number of boxes sold after lunch, we divide the total weight of cookies sold after lunch (81 kg) by the weight of cookies in each box.

Let's calculate the number of boxes sold before and after lunch:

Number of boxes sold before lunch:

To find the number of boxes sold before lunch, we divide the total weight of cookies sold before lunch (162 kg) by the weight of cookies in each box.

Let's assume that each box contains x kg of cookies.

Therefore, the number of boxes sold before lunch can be calculated as:

Number of boxes sold before lunch = Total weight of cookies sold before lunch / Weight of cookies in each box

Number of boxes sold before lunch = 162 kg / x kg

Number of boxes sold after lunch:

To find the number of boxes sold after lunch, we divide the total weight of cookies sold after lunch (81 kg) by the weight of cookies in each box.

Therefore, the number of boxes sold after lunch can be calculated as:

Number of boxes sold after lunch = Total weight of cookies sold after lunch / Weight of cookies in each box

Number of boxes sold after lunch = 81 kg / x kg

Now, let's solve these equations to find the number of boxes sold before and after lunch.
