Help-I'm stuck on this system of equations problem

[kengie]

girl volunteers 40 hours over course of school year. The hours include serving a soup kitchen, picking up trash at a park and collecting toys. She spends 4 times as many hours collecting toys as picking up trash, and 2 hours less serving at the soup kitchen than picking up trash. I have to write a system of equations to represent the info given, using variables as s,p and c for hours of serving at a soup kitchen , picking up trash and collecting toys. I am racking my brain. I need to get this done by tomorrow. Any help is welcome

"girl volunteers 40 hours over course of school year."
s+ p+ c= what?

"She spends 4 times as many hours collecting toys as picking up trash"
c= 4 times what?

"and 2 hours less serving at the soup kitchen than picking up trash."
s= what- 2?
