   ??? Any reason why we should?
   
   1) This looks like homework, not something you are just interested in.
   
   2) Everything you ask here can be done by using simple formulas. What are they?
   
   Show what you have done yourself so we will know where you need help.
   
   I am moving this to the homework section.
