Claudia offers art classes to kids and charges $10.00 for her one-hour class. If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make? Let's think first. Chain of thought:
Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20 / 2 = 10 kids. She has 20 kids on Saturday and 10 kids on Sunday for a total of 20 + 10 = 30 kids. She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10 * 30 = $300.00.
Therefore, the answer is 300.
