I don't think you need to do anything special for this question. But do be careful how you read it.
Total number of instruments = 63
Number of woodwinds = 21
Number of non woodwinds = 63 - 21 = 42 non woodwinds.
What you have to be careful about is that this is not the answer.
It says how many more .... So now you have to do another subtraction.
Total number more = Number of non woodwinds - woodwinds.
Total number more = 42 - 21
Total number more = 21 <<<< Answer

Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
m * 4 = -1
Divide by 4
m = -1/4
The slope of a line that is perpendicular to a line that has a slope of 4 is -1/4
