Lady Bird uses 1 1/4 cup flour to make 9 biscuits. She’s hosting this month's Junior League club which has 18 members and wants to make sure she allows 2 biscuits per guest. How many cups of flour will Lady Bird need? Let's answer step by step:

There will be 18 members and she wants to allow 2 biscuits per member so that’s 18 * 2 = 36 biscuits. Her biscuit recipe yields 9 biscuits and she needs to make 36 biscuits so she needs to make 36 / 9 = 4 batches of biscuits. 1 batch of biscuits uses 1 1 / 4 cup flour and she needs to make 4 batches so she will use 1.25 * 4 = 5 cups of flour. The answer: 5.
