Answer:
[tex]$74.3[/tex] is the total amount.
Step-by-step explanation:
The first step in this problem is to figure out how much of a tip was left. To find that out, you need to multiply the percentage by the total of the meal.
[tex]63 * .18 = 11.34[/tex]
We know that 11.34 was how much of a tip that was left,
To figure out the total amount that was spent, you would add the total amount and the tip.
[tex]63 + 11.34 = 74.34[/tex]
