In this table, you have to look at multiple things in the table. So you have to look at where it says Under 40 <em>and</em> that don't read the paper. So according to what I learned with this, you would have to do 36/40 and then get 0.9 which would be in percent form: 90 %.
I would recommend looking at another person's response also, before you submit this question. But hope this helps!
