Marvin is making lemon bread and pumpkin bread for a school bake sale. He needs 4 1/4 cups of flour for the lemon bread and 1 1/2 times as much flour for the pumpkin bread. He only has 2 1/8 cups of flour left in his pantry, so he buys a new bag from the grocery store. How much flour will marvin use from the new bag?
