James paves a new parking lot. It is 400 feet by 500 feet. Only 80% of that is useable for parking. It takes 10 square feet to park a car. How many cars can be parked?
Thoughts? Step-by-step reasoning:
User
The parking lot is 400 * 500 = 200,000. There are 200,000 * .8 = 160,000 square feet of parking space. That means he can park 16,0000 / 10 = 16000 cars.
Thus, the answer is 16000.
