ANSWERS 1. Consider the trade-story as if it describes two separate trades‚ where: In the first trade‚ the man buys something for $60 and sells it again for $70‚ so he makes a profit of $10. In the second trade‚ the man buys something for $80 and sells it again for $90‚ so he makes again a profit of $10. Conclusion: The man makes an overall profit of $10 + $10 = $20. You can also look at the problem as follows: The total expenses are $60 + $80 = $140 and the total earnings are $70 + $90 = $160
