I am really dedicated to studying, but I do not feel like I am improving. I struggle the most with word problems. How do you recommend I correct this?

What I would do is underline what the question is asking and any numbers involved. For me this clears up the whole word problem and makes it so much easier to solve

how is 15%=1.15? explain this please I don't understand the first example

i don't know the question you are talking about, but usually when they ask you for a 15% INCREASE in say x... then you write 1.15x.... for example, they ask you to find out the initial price of a commodity which was later on increased by 15% where the customer ended up paying say $200. then you take initial price of the commodity as X and then add it by 15% of X and equate it to $200.... It'll look like this: X + 0.15X = $200, therefore 1.15X = $200, therefore initial price of the commodity would be X = 173.91304348 or $174 (approximated value).... hope you understood what I said... If not then just try to apply my method in the sums you try....

I have limited time to study. I'm not sure what my strengths and weaknesses are. What do you suggest I do?

Hey, anwargadhi! The first thing that you should do is take a diagnostic test. Grade your test, see where you struggled, look over the answer explanations of how they figured the answers. After you have done this, focus on the areas where you struggled and work on them as much as you can. If you feel like you have gotten a good understanding of those areas after a while, you can practice some of the other areas where you did better. Just make sure to focus on the area where you struggle first, and work on that area until you have a good understanding of it. Hope this helps you!

What do you do after you find the 15% of 299? I know it is 260, but what did you do with the 75% to get 455?

You don't find the 15% of 299, you find the wholesale price, in which itself plus 15% is equal to 299. Let's say that the wholesale price is x, then x + 15/100x is equal to 299. x + 0.15x = 299 1.15x = 299 x = 260 It says then that the normal price is the wholesale price plus 75%, so we want to find x + 0.75x which is equal to 1.75x and then we can substitute x = 260 so we get 1.75 * 260 = 455.

May I ask why the first one is 1.15x instead of 0.15x. I have a faint understanding of it but I truly don't know.

Hey! I understand how this can be a little bit confusing. But, hopefully, I can explain it to you! Basically, *15%* means *15/100*. In decimal form, this is *0.15*. But, when you are adding *15%*, you are adding *15%* to the first *100%* that was there already. *100%* as a fraction is *100/100*, also known as *1*. 1 + 0.15 = *1.15*, and that is how we arrive at our answer! Hope this helps!

Lesson 2: Inside the SAT Math Test

The SAT Math Test: Problem Solving and Data Analysis

Google Classroom

In this series of articles, we take a closer look at the SAT Math Test.

SAT Math questions fall into different categories called "domains." One of these domains is Problem Solving and Data Analysis.

You will not need to know domain names for the test; domains are a way for the College Board to break down your math score into helpful subscores on your score report.

Problem Solving and Data Analysis questions might ask you to create an appropriate equation from a word problem, convert units, or understand the meaning of different numbers or variables in an equation. You might need to use the different properties of operations (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction = PEMDAS).

Problems in this category may require you to use ratios, rates, and proportions. In college and beyond, you will need to interpret and synthesize data, so these are skills that are well worth developing!

Just a few examples of problems you will be asked to solve:

Converting units (for example changing km/hr to meters/second)
Choosing appropriate graphical representations for data sets
Interpreting the slope and intercepts of a line
Computing and interpreting probability
Evaluating statistical claims or the results of a study

Using percentages in a variety of contexts, including discounts, interest rates, taxes, and tips

Example

A furniture store buys its furniture from a wholesaler. For a particular table, the store usually charges its cost from the wholesaler plus 75, percent. During a sale, the store charged the wholesale cost plus 15, percent. If the sale price of the table was dollar sign, 299, what is the usual price of the table?

Comparing distributions

Example

Scores of Two Classes in a Quiz

The dot plots above summarize the scores that two classes, each with 24 students, at Central High School achieved on a current events quiz. Which of the following correctly compares the standard deviation of the scores in each of the classes?

(Choice A)
The standard deviation of the scores in Class start text, A, end text is smaller.
(Choice B)
The standard deviation of the scores in Class start text, B, end text is smaller.
(Choice C)
The standard deviation of the scores in Class start text, A, end text and Class start text, B, end text is the same.
(Choice D)
The relationship cannot be determined from the information given.

  You don't find the 15% of 299, you find the wholesale price, in which itself plus 15% is equal to 299.
  
  Let's say that the wholesale price is x, then x + 15/100x is equal to 299.
  
  x + 0.15x = 299
  1.15x = 299
  x = 260
  
  It says then that the normal price is the wholesale price plus 75%, so we want to find
  x + 0.75x
  
  which is equal to 1.75x
  and then we can substitute x = 260 so we get
  1.75 * 260 = 455.

  No, you're free to take the SAT as many times as you like. However, it'll look much better on your college application if you score high on your 1st or 2nd attempt rather than on your 4th or 5th, which is what I believe your teacher was trying to say; however, the way it was said made it seem like you only have one shot at this. Hope this clears things up :)
