Hi Allen

Okay, 115% of 100 is 115, right? And 15% off of 100 is 85, right? How I was taught to arrive at those answers was to multiply 100 by 1.15 to get a 15% larger number. I was also taught that one multiplied 100 by (1-0.15) to get a 15% reduction. Been doing it that way since I was a sprout.

So: A Sell would be at 115 for a stock was priced at 100
A buy would be at 85 for a stock priced at 100.

However the results are different if you divide 100 by 1.15 to get the buy price and divide by .85 to get the sell price.

100/1.15 = 86.956
100/.85 = 117.647
