A good way to make money is to think of something to sell that will make you a profit. Opening a lemonade stand during summer can make you a profit if you keep track of the costs of the ingredients and the amount of money you will charge for each glass. If you add ice to the lemonade, you can sell more glasses because there will be less lemonade in each glass. Adding different ingredients such as blueberries will make your lemonade more appealing, and you may be able to sell more!
