Hi everyone, Alexis Avila Founder of Prepped & Polished LLC, here in
Boston. One way to boost your math score on the SAT test is to try a plug
in technique for math problems that involve variables. I am going to show
you how you can get hard level SAT math questions correct by using a plug
in technique.The question is, if Y and X are positive numbers, what percent of Y is X.
The first thing you are going to do is plug in for Y and X. Let’s make Y =2
and X =1 for this specific problem. Now you are going to reread the
question with the numbers that you assigned for the variables. So, if 2 and
1 are positive numbers, what percent of 3 is 1? The question now is what
percent of 3 is 1, pretty easy, right? That’s 33.3333%. We are just going
to say 33. That’s what I circled here is our target answer. Which means the
correct formula will render 33.Finally, plug in your numbers for Y and X into all of your answer choices
and eliminate the answers that will not give you 33, which is your target
answer. Just a shortcut here, if you plug in your numbers in A, B, C, and
D, these equations will not give you 33. But, if you go to E which is 100X
over Y + 1, let’s solve it. 100 X is 100 times 1 over 2 + 1 which is 3.
So, 100 over 3 is 33, a perfect match to your target answer. Go with choice
E and move on through the test. As you can see you make harder problems
easier for yourself when you utilize the plug in technique. Good luck on
your SAT and I will talk to you soon.
