Huey's Hip Pizza sells two sizes of square pizzas: a small pizza that measures 14 inches on a side and costs $10, and a large pizza that measures 21 inches on a side and costs $20. If two friends go to Huey's with $30 apiece, how many more square inches of pizza can they buy if they pool their money than if they each purchase pizza alone?
Choose the correct option:
A) 5 square inches B) 10 square inches C) 49 square inches D) 25 square inches E) 350 square inches
In the first case each can buy one pizza of $10 and one pizza of $20.   In square inches that would be (14*14=196) for the small pizza and (21*21=441) for the large pizza. In total sq inches that would be  (196+441)*2=
