Calculating the Amount of Yarn Used for Mittens

To calculate the amount of yarn used for the mittens, we can start by determining the total amount of yarn used for the sweater and then subtracting that from the total amount of yarn available.

Given: - 3 balls of white yarn, each weighing 50 grams - 4 balls of blue yarn, each weighing 100 grams - The sweater was made using some of the yarn, and the remaining yarn was used for the mittens

Let's calculate the total amount of yarn available: - Total white yarn = 3 balls * 50 grams/ball = 150 grams - Total blue yarn = 4 balls * 100 grams/ball = 400 grams - Total available yarn = 150 grams (white) + 400 grams (blue) = 550 grams

Now, we know that the sweater used 450 grams of yarn, so the remaining yarn for the mittens can be calculated as: - Remaining yarn = Total available yarn - Yarn used for sweater - Remaining yarn = 550 grams - 450 grams = 100 grams

Therefore, 100 grams of yarn were used for the mittens.
