The point is that $45 is already a retail price, so a price after 80% mark up on wholesale price. Say wholesale price x, then 1.8x=45 --> x=25. In order to achieve a 100% markup a retail price should be 2*25=$50, so $5 more.

Mark up = 80%.

1.8x=45 --> x=25.

In order to achieve a 100% markup a retail price should be 2*25=$50, so$5 more.

Hope this helps.

I'm going to need a little more help here ! You said initial price was 45$. Then markup was 80% hence final price would be 45+((80/100)*45) . This would lead to 81.
100% markup from 45 should mean 90. hence 90-81= 9.
This was my initial approach. When i couldnt find 9 in the options, then i went on to do 1.8x=45
But i still dont get why the language of the question doesnt mean that the initial price was actually 45.
Per your equation , 1.8x=45 , it seems that 45 was the final price after the markup .

The point is that $45 is already a retail price (initial price), so a price after 80% mark up on wholesale price.

I think it sounds vague, but its actually correct, when the sentence says, "marked it up", it refers to 'wholesale price'.. marked it up to get the initial price of $45. Initial price is not wholesale price here.. its the price after mark up. BTW this can be solved without any effort. 80% is 4/5 of the wholesale price. so the current ratio of sale price to cost price is 1+4/5 = 9/5. When we see 9/5 and$45, its rings a bell.. so the wholesale price ( cost) must be 25 and to get a 100% markup, the sale price should be 50, so the price needs to be increased by 5.

Hi All,

The first sentence in this prompt clearly states the 'order' of events:

1) A retailer bought a shirt at wholesale (let's say X dollars)
2) Marked it up 80%.....1.8X dollars
3) To its initial price of $45 From this, we have an algebra equation: 1.8X = 45 From here, the math can be done in a couple of different ways.... You COULD solve for X then redo the entire calculation to figure out what the increase would need to be for the price to be marked up 100% OR..... You COULD set up a ratio.... Since we need a 100% mark-up, we're looking for the value of 2X. This means that we want to increase 1.8X by 0.2X.... 1.8X/0.2X = 45/Y where Y is the amount that the price of the item would need to be MARKED-UP to make the markup 100% 1.8X/.2X = 45/Y 9/1 = 45/Y 9Y = 45 Y = 5 Final Answer: GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at: Rich.C@empowergmat.com The Course Used By GMAT Club Moderators To Earn 750+ souvik101990 Score: 760 Q50 V42 ★★★★★ ENGRTOMBA2018 Score: 750 Q49 V44 ★★★★★ Retired Moderator Joined: 19 Mar 2014 Posts: 917 Location: India Concentration: Finance, Entrepreneurship GPA: 3.5 Re: A retailer bought a shirt at wholesale and marked it up 80% [#permalink] ### Show Tags 26 Jun 2017, 10:30 A retailer bought a shirt at wholesale and marked it up 80% to its initial price of$45.

Let the wholesale price for this shirt be x

$$x + 0.8x = 45$$

$$1.8x = 45$$

$$x = \frac{45}{1.8}$$

$$x = 25$$

So, wholesale price = $25, 100% increase will make the price =$ 50

Diff: $$50 - 45 = 5$$

Kind of confused here. A 80% markup over $45 would be$81, a 100% markup would be $90, so in order to get a 100% markup he would need to increase the price by$9?! Either there's a mistake in the question or I misunderstood it.

We are asked increase the price to achieve a 100% markup.
From the question, we already increased to to 80% markup.
We need to increase the initial price by more 20% to achieve the 100%.
180% = 45
notice that both numbers (180 and 45) are divisible by 9
20% = 5

Stem states that 1.8x = 45
100% mark up is 2x, i.e an additional 0.2x

So, (0.2x/1.8x)*45 = 5

This is how i solved it:

C.P = 45
M.P = 45*1.8 = 81 (80% mark up)
In order to achieve a 100% mark up

(45+x) * 1.8 = 100
we need to find x

So solving the equation, we get :

x = 5
Answer = E which means if 45 is increased by 5 then it will be a 100 percent mark up.

Solution

Given
• A retailer marked up the price of a shirt by 80% to 45.

To find
• By how many more dollars does he need to increase the price to achieve a 100% mark-up

Approach and Working out
• Price after 80% markup= 45
o So, 1.8* Cost price = 45
o Cost price = 45/1.8 = 450/18 = 50/2=25
• So, the price after 100% mark up = 50

Hence, the price of the shirt if increased by \$5 will give 100% mark up.

Thus, option E is the correct answer.
