Answer:
Nate should leave a tip of $6.30.
Explanation:
Since the total bill was $52.43, and Nate wants to leave a 12% tip, you would have to find out what 12% of 52.43 is. To find this out you would multiply 52.43 by 12%. This is 6.2916. So, to leave the waiter a 12% tip, Nate would leave about $6.30.
