Question: 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?
Total square footage is 16 * 10 = 160 square feet. . There are 3 + 3 = 6 rooms. 6 - 1 = 5 of them are the same size. If x is the size of the normal room then the square footage of all rooms is 5x + 3x = 8x. So each room is 160 / 8 = 20 square feet. So the living room is 20 * 3 = 60 square feet.
The answer: 60

Reasoning and answer: If it takes on average 3 minutes to get dressed, then it takes 15 minutes total on the school week because 5 x 3 = 15. Thus far this week it has taken him 13 minutes to get dressed because 2 + 4 + 3 + 4 = 13. To tie his previous method, he needs to take 2 minutes on Friday because 15 - 13 = 2.
The answer: 2

Reasoning and answer: The total number of hours that Rafael has worked by Tuesday is 8 + 10 = 18 hours. To complete his assigned work hours, Rafael works 20 hours more, making his total weekly hours to be 18 + 20 = 38 hours. Since he is paid $20 per hour, he makes $20 * 38 = $760 a week.
The answer: 760
