A rental company has a fleet of 25 vehicles, consisting of cars and vans. Cars can seat 5 people, and vans can seat 8 people. The total seating capacity of the entire fleet is 155.
How many vans are in the fleet?
- 10 (correct answer)
- 12
- 15
- 25
Explanation: Let 'c' be the number of cars and 'v' be the number of vans.
We can create a system of two equations:
Distractor C is the number of cars (c = 25 - 10 = 15). Distractor B is a plausible result of a calculation error. Distractor D is the total number of vehicles in the fleet.
