An item that has been marked up sells for a profit. If an item sells that has been marked down, can it still produce a profit? E
lana66690 [7]

Yes, it can. On most things (especially clothes and furniture) they will be already marked up 100% before the mark down. For example; even if they have a, let's say, 40% off sale on the shirt, they will still make a 10% profit off the shirt. So pretty much in most cases, there will still be a profit out of the merchandise.

This is for the Journal Activity on e2020. The words required to pass the written response are as follows: Yes, profit, less, more, greater, much.

Use any 2 of those words in your response and you will pass it.

Have a good day everyone! :)
