Bill Jackson teaches at 2 schools. In the last 30 school days he taught in one of the schools for 2 more days than in the other school How many days did he teach at each of the 2 schools in the last 30 school days
I think the answer is 17, and 13. I think so because 30 divided by 2 is 15 (half), and because he taught one two more days than the other, I added two to one, and subtracted 2 from the other.
