This seems confusing, like part of the question was cut off, but I'll try my best!
Answer: (For Part A)
I'm gonna assume that the $25.30 is the sum of all food and beverages.
So, if that's the case, the bill should be $27.32
Explanation:
The meals tax is 8%, so all you have to do is multiply 25.30 (or 25.3) with 0.08 (8%) to get 2.024. Then you add 2.024 to the original number;
25.30 + 2.024 = 27.324
Finally you round to the nearest cent. So you get $27.32
However this might be incorrect because it looks like a part of the question is missing.
