Suppose you go to dinner with 3 other friends and spend $78.66. If the group wants to tip 17%, then find the amount of the tip. Round your answer to two decimal places.

To calculate the tip, you need to find 17% of the total dinner bill of $78.66. Here's how you do it:

\[
\text{Tip} = \text{Total Bill} \times \text{Tip Percentage}
\]

Substitute the values:

\[
\text{Tip} = 78.66 \times 0.17
\]

\[
\text{Tip} = 13.3722
\]

Rounding to two decimal places:

\[
\text{Tip} = 13.37
\]

So, the amount of the tip is **$13.37**.
