**Bill**, Monday, March 7, 2011 at 12:04amfirst you need to find 85% of 40 questions. turn 85% into the decimal .85... you do that by dividing 85 by 100. the formula is x=.85(40) and that gives you x=34. so now you know that Wendy had 34 out of 40 questions right, so now to find out how many she had wrong you subtract 34 from 40 and get 6. Wendy did not answer 6 questions correctly. Another faster way of doing this would be to realize since she had 85% right, then you know she had 15% wrong, so x=.15(40) , so x=6. Hope this helped.
