Answer 2

Calculation of Grape Sales

To calculate the amount of grapes sold on the first day, we need to determine the weight of each box of grapes.

According to the information provided, 9 identical boxes of grapes were sold on the first day, and 11 identical boxes were sold on the second day. The total weight of grapes sold over the two days is 340 kg.

Let's assume that each box of grapes has the same weight. To find the weight of each box, we can set up the following equation:

9x + 11x = 340

Where 'x' represents the weight of each box of grapes.

Simplifying the equation, we have:

20x = 340

Dividing both sides of the equation by 20, we find:

x = 17

Therefore, each box of grapes weighs 17 kg.

To calculate the weight of grapes sold on the first day, we multiply the weight of each box (17 kg) by the number of boxes sold (9):

Weight of grapes sold on the first day = 17 kg/box * 9 boxes = 153 kg.

So, 153 kg of grapes were sold on the first day.
