Answer: $65
Explanation:
 The total amount paid will be the meal cost plus the tip. Since the tip is 20% of the meal cost, and the meal cost is equal to 100%, we will find 120% of $54. We will do this by multiplying.
 120% of $54
 1.2 * 54
 64.8
 Now, we will round to the nearest dollar (ones place) as instructed.
 $64.8
 $65
