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?
Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20/2 = <<20/2=10>>10 kids
She has 20 kids on Saturday and 10 kids on Sunday for a total of 20+10 = <<20+10=30>>30 kids
She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10*30 = $<<10*30=300.00>>300.00
