Final answer:
Riding with a friend for 6 tickets results in a cost of 3 tickets per person, which is less than riding alone for 4 tickets per person. Thus, it is the better deal if you want to save tickets and enjoy the ride together.
Step-by-step explanation:
To determine which option is the better deal with your limited tickets, you should compare the cost per person for each option. If you ride with a friend for 6 tickets, the cost per person is 6 tickets divided by 2 people, which is 3 tickets per person. If you ride alone for 4 tickets, the cost is 4 tickets per person. Therefore, riding with a friend is the better option in terms of ticket conservation.
