Georgie needs 3 avocados to make her grandmother's guacamole recipe. If she already had 5 avocados and her sister buys another 4 avocados, how many servings of guacamole can Georgie make? Give me reasons, before answering the question
Altogether, Georgie has 5 + 4 = 9 avocados. She can make 9 / 3 = 3 servings of guacamole. So the final answer is 3.
