You have 8 full gallons of lemonade to sell that your mother donated to you. You can sell cone-shaped cups of lemonade at 75 cents a cup or you can sell square-based pyramid cups of lemonade at 70 cents a cup.

1. How many paper cups of each shape would you need if each customer uses one paper cup? (Hint: 1 gallon = 3785 cm³)

2. How much money would you have after selling all the lemonade for each type of cup?
