After a 10% loss, a fund had $2,790; what was the balance before the loss?

Okay, so you're trying to figure out the balance BEFORE the 10% loss and due to the 10% loss your balance is now 2,790 right?

27900

So I'm actually not sure, do you have answer choices?

I need the answer choices if you do so I can get an idea.

0.90 x = 2790

The answer is 27900

Geez dummy really is a dummy.
