On warm days, the correct lemonade recipe is 8 lemons, 4 cups of sugar, and 3 ice cubes. When it gets cooler, remove some ice cubes from the recipe. When it gets as cold as 10 to 20C, lower the price to at least 0.50. Only buy the ice in the amounts that you need, as it is only good for a day. For the other supplies, always buy in bulk when you are low on them. This will help you in the long run. Invest about 3.00 per day on advertisements; people will visit your stand, but the lines will not get so long that customers will leave. To move up to the next level of rent, adding a 0 to the daily rent. That will tell you when it is appropriate to move up.

A good way to get money is as follows: 6 lemons, 3 cups sugar, 4 ice cubes, price 1.80. This is good for either the train station or the downtown area, and is always liked by the customers.
Also try the following recipe: 6 lemons, 3 cups of sugar, 4 ice cubes, price 1.50. This is good for the stadium. It is possible to generate 900 customers per day and make 1200.
A very good recipe is 7 lemon, 4 sugar, and 5 ice. It works even when it is cold/hot.
Put nothing in your recipe, meaning no sugar, no lemons, and no ice. Rent suburbs, which costs nothing. The only things you need to buy are cups and other required normal supplies, and you still need to advertise. Now people will always buy your lemonade. Custumer satisfaction will drop, but for some reason your popularity and cash will go up. You may lose a bit of money in the beginning, but eventually you will start to make approximately 10 to 15 dollars a day.
