Explanation for Question 11 From the Math (Calc) Section on the 2020 October Sat
So question number 11 is asking me how many teachers are predicted to be 2 in the high school. In 2017, we can see that they're asking us about 3 teachers. So we want to use the equation that is meant for teachers T 4 event. And that equation is Tia then is equal to 80 plus N where 5 N is the number of years after 2002. 6 And if I'm in 2017, that means that 15 years have 7 passed since 2002. So my N is equal to 15. 8 That means all I have to do is 80 plus 15, 9 which gives me our correct answer of C 95.
