Answer: 56.5
Explanation:
We can use a proportion to solve this problem. A proportion is an equation that shows two ratios are equal. The ratio of grams of protein to grams of pasta is constant, so we can use this to set up our proportion.
We know that a 32-gram serving of pasta contains 4 grams of protein. So we can write:
4 grams of protein / 32 grams of pasta = x grams of protein / 454 grams of pasta
where x is the number of grams of protein in a 454-gram box of pasta.
To solve for x, we can cross-multiply:
32 grams of pasta * x grams of protein = 4 grams of protein * 454 grams of pasta
Simplifying this equation gives:
32x = 1816
Dividing both sides by 32 gives:
x = 56.5
Therefore, there are approximately 56.5 grams of protein in a 454-gram box of pasta.
