Intital fee to rent a car = $25
Fee charged per hour to ride the car = $30
Cost of renting a car for three hours :
= Intital fee + cost of renting the car for 3 hours
[tex] =\tt 25 + 30 \times 3[/tex]
[tex] =\tt 25 + 90[/tex]
[tex] =\tt\$ 115[/tex]
Thus, cost of renting the car for three hours = $115
Therefore, the cost of renting a car for 3 hours at the airport = $115
