How many tickets with different points of origin and destination can be sold on a bus line that travels a loop with 26 stops?

Answer:
The number of tickets with different points of origin and destination that can be sold on a bus line that travels a loop with 26 stops is 650.
Step-by-step explanation:
For answering this question, we can use the following reasoning:
Every of the 26 stops of the bus line has the option to sell tickets to all of the 25 remaining destinations, therefore the number of tickets would be:
26 stops * 25 destinations
26 * 25 = 650
The number of tickets with different points of origin and destination that can be sold on a bus line that travels a loop with 26 stops is 650.
