To find the cost of one ticket, we first need to determine how much was spent on insurance in total and then subtract that from the total amount paid for the tickets.
Oksana and her 3 friends make a total of 4 people attending the concert. The insurance cost per person is $14.
-
Calculate the total insurance cost: \[ \text{Total insurance cost} = 4 \text{ people} \times 14 \text{ dollars/person} = 56 \text{ dollars} \]
-
Calculate the total amount spent on tickets: \[ \text{Total ticket cost} = \text{Total cost} - \text{Total insurance cost} \] \[ \text{Total ticket cost} = 540 \text{ dollars} - 56 \text{ dollars} = 484 \text{ dollars} \]
-
Finally, divide the total ticket cost by the number of people to find the cost of one ticket: \[ \text{Cost of one ticket} = \frac{\text{Total ticket cost}}{4 \text{ people}} = \frac{484 \text{ dollars}}{4} = 121 \text{ dollars} \]
The cost of one ticket is $121.
