Answer:

There's a parking lot that is 600m² big. The lot must be able to hold at least 3 buses and 10 cars.

Each car takes up 6m² and each bus takes up 30m².

However, there can only be 60 vehicles in the lot at any given time.

The cost to park in the lot is $2.50 per day for cars and $7.50 per day for buses. The lot must make at least $75 each day to break even.

What is a possible car to bus ratio that would allow the lot to make profit?
