I see no underlined digit. But here:
6 - Hundred place.
4 - Tens place.
8 - Units/ones place.
I believe the total is $211.27.
After doing multiple searches on the internet, I believe that tax rate is a percentage of the product that is added to the total cost.
9 percent of 193.84 is 17.4456, which rounds up to 17.44, and 17.44 added to 193.84 is 211.27.
