Hi all,

Are you as smart as an 8th grader?

I pay my son 8 cents for every problem he gets correctly solved and fine 
him 5 cents for each incorrect solution. At the end of 26 problems, 
neither owes anything to the other. How many problems did the boy solve 
correctly?

What the algebraic solution here?
Paul
