Should Americans be allowed to voice their opinions on global politics?

This is your assumption. You don’t know that he didn’t already have a separate cash reserve

he broke even i think

He buys horse for 60
sells it for 70, he made 10 in profit
He buys the horse for 80, he is now 10 in debt, he sells it back for 90, so he pays the 10 debt and has 80 dollars.
he has broke even

$0. No wealth was created. The idea of selling at a profit being productive is a Jewish creation.

Wtf moron. Count what he spent on horses. Count what he sold them for. The difference is 20. How is this even hard? There is no other info here so the answer is 20.

Do peoples brains really work this way

i swear to God the posts in this thread are infuriating

Wrong. The price increase was caused by inflation so the guy didn't really earn anything.
Correct answer is he broke even.

Jesus fucking christ.

Buys for 60
-60
Sells for 70
+70
-60 + 70 = 10
He buys again for 80
10 -80 = -70
Sells for 90
-70 +90 = 20
The answer to this easy fucking question is 20 dollars.

The riddle doesnt say he only had the original 60 dollars to spend. Youre making assumptions.

>everybody in this thread forgetting the 34%APR that he sold the horse at

Whether you pretend it's in different accounts or the same account, It's all ultimately his money so all you are doing is engaging in an accounting fiction.

The first 60-70 transaction is irrelevant because the second purchase starting at 80 eats up whatever profit he made on the first sale. So it's more proper to look only at the second transaction, which is a total profit of $10.

He did ln’t pay income or property tax on the horses so the feds took his horses and he’s now in jail.

I think he ends up making $10

He spent 140 for both purchases.

He made 160 from both sales.

$20 ahead

He’s still a slimy merchant who should’ve used the horse to plow his field and grow some food.

This is a retarded question that has no answer because an extra $10 was entered into the equation without specifying where it came from.
Was the money from a recent business loan? If so what’s the interest rate on the loan? How long did it take him to pay off the loan and at what interest rate? If it’s a business loan then that $10 isn’t really costing him $10, but more in the long run.

It's obviously $30. He started with x-60, and ended with x+90. Anyone who didn't get this is obviously retarded.

It's asking how much money he made, not how much money he has. We can assume he had no money before he started buying and selling horses.

So it would be 0-60+70-80+90=20.

He has $100 to start.

He buys a horse for $60. He now has a horse and $40.

He sells the horse for $70. He now has $110.

He buys the horse for $80. He now has a horse and $30.

He sells the horse for $90. He now has $120.

$120 is $20 more than the original $100.

He made $20 profit.

*made no money FUCK

He made 20 in reality. Government will tax him. So around 14. Less if he borrowed the 60 at the start. Not really worth it.

>buys 60
>sells 70
>10 profit of 70

>buy 80
>minus 10 because you had 70 when you bought 80
>minus 10 plus 90 is 80
80

This is the only correct answer.

Its up to interpretation.
If you use one reasoning method you get 20 dollars
If you use another method you get 90 dollars

No malice involved but can i ask you whats your age and job (or field of study if you dont work yet)?
