PLEASE SHOW WORK! $2.$ A local produce stand decided to extend their season by selling Christmas trees in November and

December. The stand$$s owner purchased $500$ locally grown Christmas trees. They cost $$10$ each, and

were priced at $$50$ each. Unfortunately, the trees did not sell as well as expected and the owner

needed to take markdowns of $65\%$ to sell them.

What is the initial margin percent on the Christmas trees? What is the maintain margin percent?
