## Comment on

Finding x Percent of y## Sir, the way you teach and

## HI BRENT,can u pls explain

If a ticket increased in price by 20%, and then increased again by 5%, by what

percent did the ticket price increase in total?

## Sure thing!

Sure thing!

Let's say the ORIGINAL ticket price is $100

After a 20% increase, the new ticket price is $120 ($100 + 20% of $100 = $100 + $20 = $120)

After a 5% increase, the FINAL ticket price is $126 ($120 + 5% of $120 = $120 + $6 = $126)

If the ORIGINAL price was $100 and the FINAL price is $126, then the price increase is 26%

## After solving some question I

## I'm leery about saying

I'm leery about saying "always," but I can't think of an example where the "whole" does not come after the word "of"

If course there are questions like "What is 10% of 40% of 60?" but after we calculate 40% of 60, we basically treat it like a new "whole."

## If the total payroll expense

(A) $70,000

(B) $68,320

(C) $64,000

(D) $60,000

(E) $52,320

It's a easy question but I don't know what I doing . I used x /84000= 20/100 . What method should I use

## If K is 20% more than W, we

If K is 20% more than W, we can write: K = 1.20W

So, with this question, we're told that year Y's payroll expenses (of $84,000) is 20% more than in year X's expenses.

So, we can write: (year Y's payroll expenses) = 1.20(year X's payroll expenses)

In other words, $84,000 = 1.20(year X's payroll expenses)

Divide both sides by 1.20 to get: $84,000/1.20 = year X's payroll expenses

Evaluate: $84,000 = year X's payroll expenses

Answer: A

## In a certain furniture store,

A. $2,200

B. $3,450

C. $4,200

D. $4,250

E. $5,000

I used eliminating method I choose 5000-800. 4200 *5/100 for 210 then 450-240 gives 210 . This tell us it was right . How will I use your method in this

## Let x = total sales

Let x = total sales

Nancy gets 5% commission on sales that exceed $800

So, commission = 5% of (x - 800)

This means TOTAL SALARY = $240 + 0.05(x - 800)

We get: $450 = $240 + 0.05(x - 800)

Subtract 240 from both sides: 210 = 0.05(x - 800)

Divide both sides by 0.05 to get: 4200 = x - 800

So, x = 5000

## damn it. forgot to do the x

## In the united states 13 out

What percent of Cans are recycled?

pls help me understand above ques.. https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-topic/cc-6th-percent-word-problems/e/percentage_word_problems_1

## I'm not sure which question

I'm not sure which question you'd like me to answer, so I'll do both.

QUESTION 1: In the united states 13 out of every 20 can recycled. What percent of Cans are recycled?

Part/Whole = 13/20 = 65/100 = 65%

QUESTION 2 (at https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-...): An estimated 3 out of every 25 men are left-handed. What percent of men are left-handed?

Part/Whole = 3/25 = 12/100 = 12%

Brent

## Hi Brent, I need some basic

A similar step can be found on Q210 of PS in the OG 2020.

## Question link: https:/

Question link: https://gmatclub.com/forum/company-p-had-15-percent-more-employees-in-de...

I have no idea where the 250/1.2 comes in. I don't see how we'd get to that point. I also don't see any solutions that require that calculation.

Can you show me more of the solution that mentions 250/1.2?

In the meantime, here's my full solution: https://gmatclub.com/forum/company-p-had-15-percent-more-employees-in-de...

## Hi Brent,

Please explain me something.

https://gmatclub.com/forum/6-4-is-what-percent-of-105302.html#p1996182

6.4 is what percent of 16,000?

A) 0.0004%

B) 0.04%

C) 0.4%

D) 4%

E) 4.4%

What I did

x/100 * 16000 = 6.4

160x =6.4

x= 6.4/160

x=8/200

x=4/100>>> So I though that the answer is 4% because x= 4/100.

What am i missing?

## Question link: https:/

Question link: https://gmatclub.com/forum/6-4-is-what-percent-of-105302.html#p1996182

In your solution x = the desired PERCENT

This is why you converted x percent to x/100

So, if x = 4/100, then the desired percent is (4/100)% (aka 0.04%)

## https://gmatclub.com/forum

I feel like test answer would be faster, however I did used algebraic approach to find the answer:

(?/100)180 = 45, 180? = 4500, ?=450/18 which is 25

Your solution works perfectly!

## your video is pretty good,

## It takes time to master some

It takes time to master some of the techniques in this course. After all, for many students, this is the first time they've seen such techniques.
