Question

At a restaurant, the bill comes to $40. You decide to leave a 13% tip. What is the total amount you will owe for dinner and tip?

Answer 1

First, let's calculate how much is 13% of $40:

`(13)/(100)\cdot40=(13\cdot4)/(10)=5.2`

Now, let's add the tip to the original value:

`40+5.2=45.2`

So the total amount is $45.20.
