1. Here's what we need , NSS

 

y  =  kwx        and we need to find "k" thusly :

        ____

          z

 

And we know that

 

540  = k (15) (30) / 5   simplify

 

540  =  450/ 5  * k

 

540  =  90 k     divide both sides by  90

 

6 = k

 

So...the relationship is

 

y  = 6 wx

      _____

         z

2. 

Easy to solve, NSS    !!!                           

 

 

30 * 44   =  55 * C      where C is the cost per  person

 

1320  =  55 * C      divide both sides by 55

 

$24  =  C

 

This makes sense....it should cost less per person if more people go on the trip !!!
