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.

PukousMucous · 11/02/2018 08:35

$30 profit

DadDadDad · 11/02/2018 08:35

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 · 11/02/2018 08:35

What do you think the answer is OP?

Windmyonlyfriend · 11/02/2018 08:36

$10 profit in the end...isn’t it?

zen1 · 11/02/2018 08:36

He made $10?

BertrandRussell · 11/02/2018 08:36

Up 30 surely?

gabsdot · 11/02/2018 08:36

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

Pickleypickles · 11/02/2018 08:36

He earned £10
