How could the barter system still be used? a) you trade an apple for a banana at school. b) you sell your old skateboard for $25. c) you give someone your old cowboy boots. d) you work for your neighbor and she gives you $10.

Barter system- A method of exchange when no money is involved.

B and C can't be the answers because they are not exchanging anything.

D can't be the answer either because there is money involved.

So your answer is A) You trade an apple for a banana at school. because you are exchanging something with someone for something else thats not money.

Hope this Helps!!
