As for this problem, we take into consideration that it was stated that each ticket costs $26. So if Ronald bought 6 tickets, the cost for all the tickets should have been just $132. His friend bought 5 tickets which was only at $80. Both him and his friend were overcharged. Ronald was overcharged by $30 and his friend was overcharged by $40. They generally paid another ticket with a little more to top on that. This is also an important lesson that since you know the price, you can calculate it itself to avoid being overcharged.
