The tip value is based on the bill value. Hence, to find the total payment you have to <u>multiply 78 by 1.15</u> (this includes the tip, 1.15).

$\Large \text {$Total = 78 \times 1.15 = 89.7 $}$

Or you can <u>first find how many</u> 15% is from $78:

$\Large \text {$0.15 \times 78 = 11.7$}$

And then add this to $78:

$\Large \text {$78 +11.7 = 89.7$}$
