Final answer:
To make 6 servings instead of 4 servings, James will need 2 cups of potato flakes and the same amount of boiling water.
Step-by-step explanation:
To find the amount of each ingredient needed to make 6 servings instead of 4 servings, we can use a proportion:
4 servings requires 1 1/3 cups of potato flakes and 1 cup of boiling water.
Let's set up the proportion:
4 servings / 1 1/3 cups = 6 servings / x cups
To solve for x, we can cross multiply and simplify:
6 servings * 1 1/3 cups = 4 servings * x cups
8 cups = 4x
x = 2 cups
Therefore, James will need 2 cups of potato flakes and the same amount of boiling water to make 6 servings.
