Intermediate Steps Matter

So I asked a student the following question:  If five notebooks cost $7, how much does 40 notebooks cost? This is the student work that she produced:
Is this correct? How would you grade the process? I would argue that some of the intermediate steps would definitely need attention.

  1. Questioning her to clarify may be useful insight.
    She may have first divided 40 by 5 because she couldn't by 7...But, it looks like she may have first solved that she needs eight times the number of books.
    And then solved for 8 groups of books at $7 per group :)
