Answer: the price of one ticket is $70.
Explanation:
The family of four went to a theme park and spent the total of $480 on tickets, food, and souvenir.
1/6 of their money was spent for souvenirs . It means that the amount of money that was spent on souvenirs is
1/6 × 480 = $80
1/4 of their money was spent for food. It means that the amount of money that was spent on food is
1/4 × 480 = $120
Total amount spent on souvenirs and food is
120 + 80 = $200
Total amount spent on tickets is
480 - 200 = $280
Since they are 4, the price of one ticket would be
280/4 = $70
