Answer:
Total cost for 4 tickets is $66.50
Step-by-step explanation:
Let 'n' be the number of tickets
Each ticket cost $16.00 and also $2.50 one time service fee
2.50 is the initial fee that is the service fee
cost of n tickets is 16n
so the expression for the total cost is
![16n + 2.50](https://tex.z-dn.net/?f=16n%20%2B%202.50)
use this expression to find the total cost for 4 tickets
plug in 4 for n
![16n + 2.50\\16(4) + 2.50=66.5](https://tex.z-dn.net/?f=16n%20%2B%202.50%5C%5C16%284%29%20%2B%202.50%3D66.5)
Total cost for 4 tickets is $66.50
