Explanation for Question 17 From the Math (Calc) Section on the 2019 May Sat
So question 17 says of the number of juniors and seniors in the drama 2 club. The 25% who walked to school represents one eighth of the 3 total number of juniors and seniors who walked to school, 4 how many juniors and seniors walked to school? 5 So this question has multiple parts. 6 Let's just go one step at a time. So first we need to find 7 the number of juniors and seniors in the drama club. 8 So we find the drama column and go to the total. 9 And the answer is 48. So that's our starting number 48. 10 Now 25% of those people walk to school. 11 So let's multiply that by 0.25, 12 and that gives us 12. 13 Then they tell us that that those 12 people represent one eighth of the 14 total number of juniors and seniors. 15 She walked to school. So to find the total number, 16 we now need to multiply 12 by and when we do that, 17 12 times eight gives us 96. 18 And so the answer to question 17 is a 96.
