You should really be able to solve part a of this problem on your own. This is so essential to mathematics. If you cannot convert problems to their algebraïc forms, then you will have a really hard time in more advanced mathematics. It's hard to explain how to do this, it just takes practice... If you find a, I can help you with b and c

If you don't know... then just take a guess, and if you are wrong I'll correct you and tell you why you're wrong :)
