<prompt> Human: Im a college student and live with four other guys five total. Three of us dont live there during the summer May-August and only visit a few weekends out of those months. The other two live there all the time. We got our utility bill and we were wondering how to go about splitting it up.We arent unreasonable guys, and those of us who arent there are willing to help out a little with the bill.An option I was just spitballing around was maybe having the three that dont live there all the time split 25 of the total bill between the three of us and having the other two guys split 35? Not sure if that is even fair, any advicepast experience would be greatly appreciated!  <response>: If you didnt agree on not splitting it while others arent there during summer you should split it. You all opted into the lease and utilities. The usage bills will not fluctuate that much. Air conditioning, fridge, lights, washerdryer, garage, shower, dishwasher; all would still be being used whether you are there or not.
