From the table, the z-score is +1.035. That is the 85th percentile and the same z-score means that the area to the RIGHT is 0.15, since the two include all the probability and together must add to be 1.
You find the z-score by looking in the table where the four digit number is closest to 8500. That is a probability figure and that particular one is the 85th percentile. Then look left for the first two digits of the z-score and then up to get the third digit.
Look at the z-table between .8485 and .8508.
1.0 is on the left, and it is half way between 3 and 4. That makes it 1.035
