Hi, my math extra credit (I have an 81 in the class) is to make as many math problems to send to the math team for the math tournament. I need 6th, 7th, and 8th-grade problems. Each problem that the team accepts is a point for me so I would like to send 10-20 problems. Please provide 1 correct answer and 3 other logical answers as well as an explanation for each problem. Please help, I am very busy and this would be greatly appreciated.
