Answer:
$9.25 is what each ticket costed.
Step-by-step explanation:
Because he bought 6 adult tickets, and since they all costed $55.50 in total, you should divide $55.50 by 6 to get the cost of one ticket.
$55.50/6 is $9.25, so Mai's older brother spent $9.25 on each ticket.
Each ticket costed $9.25.
