a) Suppose, number of books that she needs to read = x
     As 1 book costs for 5 points, It would be:
   5x = 30
   x = 6
   So, she needs to read 6 books.

b) If she has read 7 books, her points would be:
   7 * x
   as x = 5 (point of 1 book)
   7 * 5 = 35
  So, she got 35 points.

Hope this helps!
