Ms. Sue, help me. I don't get the runners problem. Please i am helpless!!!

See below.

I mean i don' t get why 227?

because 7 ran both times.

I still do not get it

Ms. Sue or Steve can explain more.

Tutor, help me. :(

22 run in the morning. But 7 of these run at night, also. That means that 15 run only in the morning.

Can you give me a sample problem like that to see if I get.

Ms. Sue! Please!
