Step-by-step explanation:
If one adult went and the adult tickets cost 14, we can subtract 14 from 59 to see the total cost of the children's five tickets:
59 - 14= 45
Because there are 5 children, you then divide that value by 5 in order to find out the cost for one child and, ultimately, the cost of each child's ticket: 45 ÷ 5 = 9
