Explanation for Question 36 From the Math (Calc) Section on the 2020 October Sat

So question 36 is asking us about the numbers of houses painted in July 2 and the number of houses painted in August. And now the question tells us 3 that 20 houses were painted in July, and then they give us some 4 information that allows us to find the number of houses painted in August. 5 We can see that right here. So it's the in August the houses, 6 the number of houses, the crew painted was 20% more than the number painted 7 in July. So it was 20% more. 8 So they made at least 20, right? They painted at least 20, 9 and then they painted additional 20% of 20. 10 Now we have a calculator for this, right? So we can just plug in 11 0.2 times 20 and get four. So that means that in August they 12 painted 24 houses. And now we need to know what fraction of the total 13 number of houses, um, painted in July and August was painted in August. 14 So we want to do the number painted in August over the total. 15 And we know now that 24 were painted in August and the total is 16 going to be 20 plus 24, write the number in July and the number 17 in August. So that gives us 24, 18 over 44. We plug that in our calculator, 19 we get about 0.54, 20 five, or you can simply write the most simple version of this fraction, 21 which could be 12 over 22. 22 We could go even further than that. Six over 11.
