Answer: $82.55
To figure out the tip, you need to find 20% of $65
0.2×65=13
You should leave $13 for the waiter if you want to leave him exactly 20%.
To figure the tax, you need to find 7% of $65.
0.07×65=4.55
Next, add them up:
65+13+4.55=82.55
The total bill, including tax and tip, will be $82.55.
