To determine how much Ethan will pay for the bicycle during the sale, we would need to know the sale price or the discount being applied to the original price of $164. Without that information, we cannot calculate the specific amount Ethan would pay.
However, based on the options you've provided, $123.00 is the only amount that is less than the original price. If this amount corresponds to a discount, then it could be correct.
If you can provide the percentage of the discount or the specific sale price, I could help calculate it more accurately!
