Question

How much will you pay in all for the $78 lunch bill with a 15% tip ?

Answer 1

→ You will pay $ 89.7.

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

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

Or you can first find how many 15% is from $78:

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

And then add this to $78:

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