and can't understand how so many people on Facebook have it so completely wrong (and can justify it to themselves).

Without adding your reasoning, tell me what you think the answer is.

$30 profit

DadDadDad Sun 11-Feb-18 08:35:49

Financially, it's the same as:

Man buys a horse for $60, then sells it for $70. Next, he buys a cow for $80 and sells it for $90.

Does that change anyone's answer?

Ginandplatonic Sun 11-Feb-18 08:35:59

What do you think the answer is OP?

Windmyonlyfriend Sun 11-Feb-18 08:36:09

$10 profit in the end...isn’t it?

zen1 Sun 11-Feb-18 08:36:29

He made $10?

BertrandRussell Sun 11-Feb-18 08:36:39

Up 30 surely?

He made $20. $10 profit on each transaction. It you look at each transaction separately it makes more sense.
