Alyssa, Keely, and Kendall ordered 100 chicken nuggets from a fast-food restaurant. Keely and Kendall each ate twice as many as Alyssa. How many did Alyssa eat? Let's answer step by step:
To figure out this problem we need to turn it into an equation. Let’s make A the number of nuggets Alyssa ate. We know all three girls ate 100 nuggets total, so 100 nuggets = A (how many Alyssa ate) + 2A (how many Keely ate) + 3A (how many Kendall ate) or 100 = A + 2A + 3A which is 100 = 5A. Then we will divide each side by 5 to figure out how many nuggets Alyssa ate, 100 / 5 = 5A / 5 or 20 = A. The answer: 20.
