**A man buys a horse for $60. He sells the horse for $70. He then buys the horse back for $80. And he sells the horse again for $90. In the end, how much money did the man make or lose? Or did he break even?**

Answers in the forum ranged from the man making $10, $20 and $30, while others argued he broke even. So what’s the answer?

The correct way to solve the problem is to break it down and think of the two transactions as separate: -60 + 70 = 10 and -80 + 90 = 10. This means the man makes $10 with each sale, bringing the total to $20.
