Problem Analysis

To solve this problem, we need to determine how many grams of wool were used for each pair of mittens, given that 830 grams of wool were used to make 4 mittens and a scarf, with 350 grams used for the scarf.

Solution

Let's assume that x grams of wool were used for each pair of mittens.

We know that the total amount of wool used for the mittens and scarf is 830 grams. We also know that 350 grams were used for the scarf. Therefore, the amount of wool used for the mittens can be calculated by subtracting the amount used for the scarf from the total amount:

830 grams - 350 grams = 480 grams

Since there are 4 mittens, we can divide the total amount of wool used for the mittens by the number of mittens to find the amount used for each pair:

480 grams / 4 mittens = 120 grams

Therefore, each pair of mittens used 120 grams of wool.

Conclusion

Based on the given information, each pair of mittens used 120 grams of wool.
