In the 5th panel of the Candorville Comic Strip below, Lemont's girlfriend Susan tells Lemont that his math is all wrong.

How much does Lemont owe Al or how much does Al owe Lemont, assuming that they split the cost of their dates evenly?

The Candorville comic strip is no longer available.

 

Solution to the Problem:

Lemont owes Al $10.00.

Al paid $10 for the drinks (Panel 2).
Lemont paid $10 for the popcorn and drinks (Panel 3).
Al paid $5 for the nachos (Panel 3).
Lemont paid $60 for the popcorn and drinks (Panel 4).
Lemont paid $20 for the Mariachi (Panel 4).
Al paid $15 for the popcorn and drinks (Panel 4).
The total cost of their dates was $120, so each should pay $60.
Al paid $30 and Lemont paid $90, so Al owes $30 for the dates.
However, Al loaned Lemont $40, so Lemont owes Al $10.
