Answer 1

Problem: How many points?
A certain homework help website awards R user points for registration,
Q user points for an approved question, A user points for an approved
answer, and an additional B user points for an answer that is selected
as the Best Answer.
   Using an expression involving R, Q, A and B, how many points does a
registered user get for posting 10 questions, submitting 50 answers,
and having 5 answers selected as Best Answer? (All questions and
answered are approved.)
   What is the expression for the total number of points awarded for
an answer that is selected as Best Answer?

Part 1:   P = R + 10Q + 50A + 5B
Part 2:   T = A + B

Sounds like a website I would be interested in.
