Edward bought the 7 concert tickets for himself and 6 friends for a total of $168. Each friend paid Edward back for his or her t
levacccp [35]

Answer: $26

Step-by-step explanation:

Since the 7 tickets cost $168, the value of each ticket will then be:

= $168/7

= $24

Each ticket cost $24

If one friend gave him $50, the change that the friend will collect will be:

= $50 - $24

= $26

Therefore, Edward should return $26 to the person.
