In the fifth grade, 195 people rented a car for a spring outing. It is known that each van 120 yuan can take 30 people. Each bus 150 yuan can take 45.

Seat for 30 people: 195/30=6+05, that is, 7 cars are needed. Price: 7* 120=840.

Seating for 45 people: 195/45=4, that is, 5 cars are needed. Price: 5* 150=750.

If 45 people have two cars: 45 * 3 =135195-135 = 60.

Seating for 30 people: 60/30=2

* * * Cost: 3* 150+2* 120=690.

So the third one is the most economical.
