As a participant in your schools community service project, you volunteer a total of 40 hours over the course of the school year. Your volunteer hours include serving at a soup kitchen, picking up trash at several local parks, and collecting toys for needy children. You spend 4 times as many hours collecting toys as picking up trash, and 2 hours less serving at the soup kitchen than picking up trash. Write a system of equations to represent the given information. Define your variables as s,p, and c for the hours of serving at a soup kitchen, picking up trash, and collecting toys. Can you help me please? \n" ); document.write( "
