Answer 1

To calculate the total cost of Marge's dinner including a 20 percent tip, we first need to determine the total cost of the items she ordered.

Here are the individual item amounts:

- Soup: $3.75
- Shrimp scampi: $15.00
- Iced tea: $2.60
- Dessert: $4.25

Now, let's sum those amounts:

\[
3.75 + 15.00 + 2.60 + 4.25 = 25.60
\]

So, the total cost of her meal is **$25.60**.

Next, we calculate a 20% tip on that amount:

\[
Tip = 0.20 \times 25.60 = 5.12
\]

Now, we add the tip to the total meal cost to find the total cost of her dinner:

\[
Total cost = Meal cost + Tip = 25.60 + 5.12 = 30.72
\]

Thus, the total cost of Marge's dinner including gratuity is **$30.72**.
