Alexandra was out at a restaurant for dinner when the bill came. Her dinner came to $20. She wanted to leave a 10% tip. How much was her meal plus the tip, before tax, in dollars and cents?

Answer 1

To calculate the total amount Alexandra will pay for her meal including a 10% tip, we start with the cost of the meal, which is $20.

First, we find the amount of the tip by calculating 10% of the meal cost:

\[ \text{Tip} = 10% \text{ of } 20 = 0.10 \times 20 = 2 \]

Next, we add the tip to the cost of the meal to find the total amount she will pay:

\[ \text{Total} = \text{Meal Cost} + \text{Tip} = 20 + 2 = 22 \]

Therefore, Alexandra's meal plus the tip, before tax, is:

\[ \boxed{22.00} \]
