Two children are selling lemonade they are charging 1$ for a cup they only sell 10 cups

Well this isn't a grammatically correct question but if you're asking how they would split the money it would be $5 for each person.

Step-by-step explanation:

1. The 10 people buy the cups of Lemonade.

2. One cup of lemonade is $1, so that means 10 cups would be $10.

3. Then you would give half to your friend which would be $5.
