Get Jerry Back

Congratulations, you finally finished the previous nine problems for the bratty kid's extra credit. You only have four more to go but they're due tomorrow. The kid is sick of taking care of "your stupid rat" as he calls Jerry, so he's decided to give him back to you if you complete these four problems by the end of the day. But if you don't, the kid said it's "curtains for Jerry"!

Good luck!
