Final answer:

Ann needs 3.5 cups of sugar to serve 70 people with this recipe.

Step-by-step explanation:

To find out how many cups of sugar Ann needs to serve 70 people, we need to set up a proportion using the information given. The recipe serves 20 people with 1/2 cup of sugar. So, the proportion will be:

20 people / 1/2 cup = 70 people / x cups

Next, we can cross-multiply and solve for x:

20 * x = 1/2 * 70

x = (1/2 * 70) / 20

x = 3.5 cups

Therefore, Ann needs 3.5 cups of sugar to serve 70 people with this recipe.
