Answer 2

The tip is 15% of the price you are paying for the food.

You are basically looking for what number is 15% of $77.48.

To find that you will be multiplying them. But before you multiply them you have to turn 15% into a decimal.

As a decimal it would be 0.15.
Now you can multiply.

$77.48 x 0.15 = $11.622
You now round it to $11.62

Answer: $11.62
