Final answer:
The answer provides a model to show the number of red grapes Amy has and also presents a word problem that can be modeled by the equation 6 x 7 = 42.
Step-by-step explanation:
Model:
Amy has 3 green grapes. She has 7 times as many red grapes as green grapes. To draw a model, let's use circles to represent the grapes. We'll draw 3 green circles to represent the green grapes, and then draw 7 times as many red circles as green circles to represent the red grapes. Since 3 x 7 = 21, we'll draw 21 red circles.
Word problem:
If there are 6 sets of apples and each set has 7 apples, how many apples are there in total? The equation 6 x 7 = 42 can represent this word problem. There are 42 apples in total.
