Final answer:
To calculate the unit rate of granola per bag of trail mix, divide 200 grams by 12, yielding 16 2/3 grams per bag, making option (c) the correct answer.
Step-by-step explanation:
The question involves calculating the unit rate of granola per bag of trail mix. Given that there is a 200-gram box of granola used to make a dozen bags of trail mix, we want to find out how many grams of granola are in each individual bag. To calculate the unit rate, we divide the total amount of granola by the number of bags:
200 grams ÷ 12 bags = 16.666... grams per bag
This can be simplified to a mixed number: 16 2/3 grams per bag. Therefore, the correct answer is (c) 16 2/3 grams per bag.
