Im having a major brain fart right now and my brain is not thinking correctly, lol. Im figuring out some hospital bills and need to know if im right on $271.00 minus 40%. If I pay the amount in full, I can deduct 40%, so I want to make sure I get it right, or I will have to pay the whole $271.00.
Thanks, and sorry for the dumb question, lol!
