See if you can get this Maths Question right

[HeroOfPellinor]

Shopkeeper from neighbor = +100
Shopkeeper - change to customer = -79
Shopkeeper to neighbor = -100
SHop keeper - cost = -18

 

[mooncancook]

hmm... $100 to neighbor shopkeeper, $21x4=84, 100-84=16.
so $16 change to the buyer, and $18x4=$72 worth of product to the buyer.
so total loss is $100 + $16 + $72 = $188!!!

 

[amoeba]

oh, you mean the $18 is how much it cost the shopowner, I thought it meant sales price.

Then I think its $97.

 

[yokomo]

wow I got it wrong... forgot the change that he gave to the man leaving..

 

[nwfsnake]

He gave the customer $79 in change.
He gave the customer a product which cost him $18.
He gave the other shop keeper $100 back.

Now my answer is $197!

but where did the $79 in change come from?

 

[MobiusPizza]

I wonder if this is the problem of US English and UK English

Marked price mean selling price here in UK
I can't find a better word than "cost price" as indicated by my dictionary of unknown origin

I was assuming he's buying the max number of product he can buy,
but if he only buys one:

$100 to neighbor + $79 change + $18 cost = $197!!

So I'll just say $42.

i agree, it's worded so badly.

No, it's $97. But the question itself was worded like it was written by a primary schooler, so I'm not surprised most people get it wrong.

$179 in money ($100 for counterfeit + $79 in change)
$18 in cost of product
= $197

Must Repay Bank note of $100


$182

According to your analogy
-79
-18
+21
-100

That's -$176

that $79 change was never his to begin with....so you can't count that as a loss.

Sorry I was trying to be ambiguous
These type of questions are more challenging when they are confusing

Maybe I shall address the shopkeeper as Mr.X
That might be better

Think through it again.

did he really give $79 in change?

 

[HonkeyDonk]

i want to say $118.

In the end, he has to give back $100 to his neighbor and he's out of the product.

so -$100 and -$18. -$118 total.

edit: or maybe it's $115 b/c he made $3 in the sale.

But he kept $21 of the $100, the retail cost of the item.

$179

Edit for Breakdown:
-$79 in change lost
-$18 in lost product
+$21 in good money leftover

-$100 in counterfeit bill

Yeah, but that's the problem with math. You can't just say "in the end", because when you do that, you're skipping a bunch of important equations. You have to factor in EVERYTHING, math is very anal.
