Maria invited 8 friends to dinner. They are going to have "make-you-own pizza." The dough recipe serves 3 people. Here are the ingredients: \( 1 \frac{3}{4} \) cups flour \( 2 / 3 \) cup warm water 2 tsp yeast 1 tsp salt 1 tsp sugar How much water should she use to make enough dough for herself and her 8 friends?

To make enough dough for Maria and her 8 friends, they'll be a total of 9 people. Since the original recipe serves 3 people, you'll need to scale the ingredients up for 9 people. First, divide 9 by 3, which equals 3. This means you need to multiply the amount of each ingredient by 3. For the water, the original recipe calls for \( \frac{2}{3} \) cup. So, multiplying this by 3 gives: \[ 3 \times \frac{2}{3} = 2 \text{ cups of warm water.} \] So, Maria should use 2 cups of warm water to make enough dough for herself and her 8 friends! Now they're set for pizza night! 🍕
