ms. sue how did you come up with your answer? I did this. 33.80 and 2.5%

33.80 times .025 = 0.845. I don't understand what the total amt of bill is?

Your answer is correct. The discount is $0.85 (85 cents). Subtract:

33.80 - 0.85 = total amount of bill.

I subtracted 2.5% from 100% to get 97.5% = 0.0975. You're paying 97.5% of the quoted price of $33.80.
