<human>:  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?
<bot>: How many square feet is the parking lot? ** The parking lot is 400*500=<<400*500=200000>>200,000
How many square feet are in the parking lot? ** There are 200,000*.8=<<200000*.8=160000>>160,000 square feet of parking space
How many cars can be parked? ** That means he can park 16,0000/10=16000 cars
