Answer:
The total cost of her dinner including tip would be $30.72
Explanation:
Marge orders the following items on her meal.
Soup = $3.75
Shrimp scampi = $15.00
Iced tea = $2.60
Dessert = $4.25
The total cost of her dinner including gratuity is
3.75 + 15.00 + 2.60 + 4.25 = $25.60
She would like to leave a 20% tip based on her bill
Therefore, 20% of $25.60
= 0.20 × 25.60 = $5.12
Now add this tip amount to the bill amount.
$25.60 + $5.12 = $30.72
The total cost of her dinner including tip would be $30.72
