Answer:
$11.09
Step-by-step explanation:
The split will include the tip. As such, the lunch bill and the tip will be split equally among the friends.
Since there are 4 friends,
The total cost = ($36.96 + 20% × $36.96)
= $44.352
Dividing this among the 4 friends
= $44.352 /4
= $11.09
Each person pays $11.09.
