Gabrielle is baking large batches of brownies and cookies to share with her friends and family. Among other ingredients, her brownie recipe calls for 1 cup of sugar and 2 eggs and her cookie recipe calls for 3 cups of sugar and 2 eggs. Gabrielle has 20 eggs and 21 cups of sugar, and she would like to know how many batches of brownies and cookies she can bake without getting more of these ingredients. Part A

Question

Which system of inequalities can model Gabrielle’s situation, where x represents batches of brownies and y represents batches of cookies?

2x + 3y ≥ 20

x + 2y ≥ 21

2x + 2y ≥ 20

x + 3y ≥ 21

2x + 3y ≤ 20

x + 2y ≤ 21

2x + 2y ≤ 20

x + 3y ≤ 21
