Answer 2

Problem Analysis

To solve this problem, we need to find the weight of mandarins in each of the three boxes and then calculate the difference in weight between the third and first boxes.

Solution

Let's denote the weight of mandarins in the first box as x kg. According to the given information: - The weight of mandarins in the second box is x + 1.05 kg. - The weight of mandarins in the third box is (x + 1.05) + 0.7 kg.

To find the weight of mandarins in the third box, we can substitute the weight of mandarins in the second box into the expression for the weight of mandarins in the third box: (x + 1.05) + 0.7.

Calculation

Let's calculate the weight of mandarins in the third box: (x + 1.05) + 0.7.

Result

The weight of mandarins in the third box is x + 1.75 kg.

Conclusion

The weight of mandarins in the third box is 1.75 kg more than the weight in the first box.
