Final answer:
To find the cost of 3½ cups of chocolate chips, you need to determine the weight of the cups and then calculate the total cost based on the cost per ounce.
Step-by-step explanation:
To find the cost of 3½ cups of chocolate chips, we first need to determine the weight of 3½ cups. Since 1 cup of chocolate chips weighs 6 ounces, 3½ cups would weigh 3.5 * 6 = 21 ounces.
Now we need to determine the cost of 21 ounces of chocolate chips. We know that a 25-pound bag of chocolate chips costs $63.65. Therefore, the cost per ounce is 63.65 / 25 = $2.546.
Multiplying the cost per ounce by the weight of 21 ounces gives us the total cost: 2.546 * 21 = $53.466. Therefore, 3½ cups of chocolate chips would cost $53.47 (rounded to the nearest cent).
