If a man buys a horse for $60, sells it for $70, buys it back for $80, and sells it again for $90, it may seem tricky at first to figure out his total profit. Let’s break down each transaction step by step.

First, he buys the horse for $60 and sells it for $70:

– Spent: $60

– Earned: $70

In this transaction, he made a profit of $10 (70 – 60 = 10).

Next, he buys it back for $80 and then sells it again for $90:

– Spent: $80

– Earned: $90

Here, he made another profit of $10 (90 – 80 = 10).

Adding both profits together, the man made a total profit of $20 (10 + 10 = 20).
