The answer appears to be $20...

What seems to be throwing people off is the fact that the man sells the goat for $70 and then buys it back for $80, making it look like he spent 10 more dollars. But the correct way to solve the problem is to think of the two transactions as separate: -60 + 70 = 10 and -80 + 90 = 10.

The man makes $10 with each sale, therefore he earns a total of $20.

So the fact that he bought an $80 goat with $70 means what? How?

You realize that most people don't start their days flat broke?


Let's say he started the day with $100.

Bought the goat for $60. Now he has $40 and a goat.

Sold the goat for $70. Now he has $110.

Bought goat again for $80. Now he has $30 and a goat.

Sold the goat for $90. Now he has $120.

$120 is $20 more than $100, so he made a profit of $20.

How much he started with doesn't matter, of course. As long as he had the money to make the transactions, he's getting $20. It is ALL addition and subtraction, nothing more.

I didn't say $80 was profit I said $20 was profit. He began the day with $60, ended it with $80 in your scenario where he borrows $10. That's $20 profit.

Your post is nonsensical rambling.

He is just trolling breh. Ain't no breh that damn simple.

Even if he got fronted the goats he still ends up with 20 dollars. It doesn't matter if he had 0, 60 or 1000 dollars.

Y'all need to do this with actual money.

These answers are ridiculous.

I'm having a sell this weekend. I'd love to do business with most of y'all.

It's two separate transactions. Y'all thinking too much.

 

[Field Marshall Bradley]

$80 isn’t profit. We’re talking profit. That’s it. How much you made is not profit plus investment. The initial investment was $60. The second investment was $80 (ten he had to borrow). No one is going to sell you something at a loss for you to turn around and make money unless they’re an idiot.

So the second goat was $80 but dude only had $70. You don’t think the goat seller wants all his money?

I think you’re putting too much into it like I was at first... it’s 20 dollars man.

total outgoing: $60+80 = $140
total received: $70+90 = $160

profit = $20


None of the details of the transactions, such as "started with X" or "used Y together with Z to buy ITEM" are required, and only seem to complicate how some people think about this question

Looks like you gained 10 twice and lost 10 once...

Not sure why someone would look at this as 2 equations instead of 3 equations...

$10

Jesus....this shyt really has people fighting over a basic problem?

Let's look at this two ways....

EASY WAY
-60+70 = 10
-80+90 = 10
10+10 = $20 made

Now some people have been questioning how he had enough money to re-buy the goat at 80.

Alright...

MORE COMPLEX WAY
Dude starts with $60 dollars in his account (we won't assume anything else because it isn't stated in the question). This is a logical assumption.

He buys the goat. $0 in his account. Sells for $70. $70 in the account.

Goat costs $80 on the re-buy, so he needs to borrow $10 from someone (interest free since again, question doesn't say shyt about it). By borrowing money, he has 70 + 10 = $80 in his account. Buys the goat again. $0 in the account.

Sells the goat for 90. $90 in the account. Oh wait....gotta pay the friend back. He gives the 10 back...so 90-10 = $80 in the account.

Bank account at the start = $60
Bank account at the end = $80

He made $20 overall.

$20 is the only plausible answer. I don't know where y'all are throwing out these random ass numbers out, adding false conditions to the question etc. There's only one answer.
