[Video] Q22: Which of the following best approximates the average rate of change in the annual budget for agriculture/natural resources in kansas from 2008 to 2010 ?

Explanation for Question 22 From the Math (Calc) Section on the Official Sat Practice Test 1

Now question number 22 asks us, which of the following best approximates, 2 the average rate of change in the annual budget for Kansas from 2008 3 to 2010. Right? So first off let's zone in on what we're trying to 4 find here, right? We're looking from 2008 to 2010. 5 So we're specifically looking here right in these years, 6 and we're also looking for the agriculture slash national natural resources. 7 So we're looking in these three boxes and 8 they want us to approximate the average rate of change. 9 Right? So there are two key things here. 10 One it's an average. So we're trying to kind of summarize everything 11 by taking the mean of the rate of change. 12 So the average rate of change, and then we want the rate of change. 13 So what they want to know is how, I guess, 14 how, um, on average, how much on average does that budget change per 15 year? 16 Right? How much does it change per year? 17 It's let's see here over the course of one year, 18 right? There was one year here between 2008 and 2009. 19 We went from this number to this number. 20 If we plug that in our calculator, if we do 4,000 8, 4 8, 5, 8 0 7 21 minus five or 3, 5, 8, 7 0 8, 22 we get 127,099. 23 So that was the change over that one year. Right? 24 And then over this year, one year we changed a different amount. 25 Looks like we changed less, right? 4, 8, 8, 1 0 6 minus 26 4, 8, 5, 8 0 7. 27 That gives us only 2000 2, 9, 9. 28 Right? So this one is much smaller than this one, 29 but what we need to do is...
