Answer 2

$5.99

Explanation:

In this problem, Doug paid the following amount for the dinner:

`p=\$39.95`

He also left a 15% tip.

Here we want to calculate what is the amount correspondant to the tip.

In order to find this value, we have to calculate the 15% of the value of the dinner, therefore we want to find

the 15% of 39.95$

The percentage (15%) can be rewritten as fraction:

`15\% =(15)/(100)`

Therefore, the amount of the tip is

`t=(15)/(100)p`

And substituting p, we find:

`t=(15)/(100)(\$39.95)=\$5.99`

So, the tip is $5.99.
