Final answer:
To find the number of calories in 261.5 grams of cereal x, set up a proportion using the given information and solve for x. The result is approximately 162.39 calories.
Step-by-step explanation:
To find the number of calories in 261.5 grams of cereal x, we can use a proportion:
First, let's set up the proportion using the given information:
110 calories / 177.4 grams = x calories / 261.5 grams
Cross-multiply and solve for x:
- (110 calories)(261.5 grams) = (177.4 grams)(x calories)
- 28765.5 calories = 177.4 grams * x calories
- x calories = 28765.5 calories / 177.4 grams
- x calories ≈ 162.39 calories
Therefore, there are approximately 162.39 calories in 261.5 grams of cereal x.
