Maybe easier to understand is if we use the numbers from the story?
As the top level comment sees it (which again is the most logical way to interpret it), the price starts at $20. Seller gives 50% discount to buyer to bring it to $10 (50% of $20 is $10 -> $20-$10=$10). Seller then adds a 50% markup because it's their birthday too, bringing it up to $15 (50% of $10 is $5 -> $10+$5=$15).
In my interpretation all of the math is being operated on the initial $20. So it's $20 minus $10 for $10 for the discount, then $10 plus $10 for the markup.
Technically he would have to charge $15... If he would add 50% to the initial $20.
Yes, I'm a lot of fun at parties
You could make it work mathematically: the added 50% would need to be based on the initial price and not a modification on the adjusted price.
It's most logically interpreted as:
x * 1.5 * 0.5 = 0.75xBut we could see it as:
x - (x/2) + (x/2) = xI'm equally fun at parties.
I’m too.. whatever.. to do the math. How much was it initially?
x
It took me 14 hours but the math checks out guys
You didn't show your work. Half marks.
It doesn't matter if he did it, we just need know know that he tried.
100%
In my algebraic version, it's x.

Came here to say the same thing. We should hang out
Aww the first Lemmy love story
Double whammy, Boneappletea and Choosing beggar. Handled so eloquently.
*Spelling is hard
*beggar 😉
Too kind sir
I always hope these are due to aurocorrect. I refuse to believe someone thinks its "purse cent" 🥹
Just let go. Or more fancy: “Abandon all hope ye who enter the written communication”
All hope is now abandoned 🥲
Wouldn't that be $15?
What is purse cent?
A penny you find at the bottom of your hand bag.
Ham bag*
Choosing beggar
Probably meant purse scent.
