Part A: Roger is making 7 batches of blueberry pancakes. If it takes \( 1 \frac{1}{4} \) cups of blueberries to make 1 batch of pancakes, write a proportion that can be used to find the amount of blueberries that will be needed to make 7 batches. Part B: Roger says that he will need 9 cups of blueberries to make the 7 batches of pancakes. Is Roger correct? Part C: Support your answer to Part B by creating a proportion using 9 cups of blueberries, and test it using cross products.
