14.5?

14 = 83.9%

15 = 82.7%

*assuming each question is weighted the same.

A lot less than you would have gotten wrong if it was a math test.

x=87*(100%-83.33%)

x = 14.5

100% / 87 = 1.1494
100% - 83.33% = 16.67% missed
16.67 / 1.1494 per question = 14.502 questions missed
or
16.67% x 87 questions = 14.502

or
16.67% x 87 questions = 14.502

Significant figures FAIL.
