Question: Andy is checking to see if all the cars in the parking lot paid for their parking. 75% of the cars have valid tickets, and 1/5th that number have permanent parking passes. If there are 300 cars in the parking lot, how many people tried to park in the lot without paying?
Answer with step-by-step thinking: First find how many cars have valid tickets: 75% * 300 cars = 225 cars. Then find the percentage of cars with parking passes: 75% / 5 = 15%. Then multiply that number by the total number of cars to find the number with parking passes: 15% * 300 cars = 45 cars. Then subtract all the cars with valid forms of parking to find the number parked illegally: 300 cars - 225 cars - 45 cars = 30 cars.
So the answer is 30.

Question: It takes Jerome 6 hours to run the trail around the park and it takes Nero 3 hours. If Jerome runs at 4 MPH, what speed (in MPH) does Nero run in the park?
Answer with step-by-step thinking: You can find the distance of Jerome's run by multiplying the time he spends running by his speed: 4 miles / hour * 6 hours = 24 miles. Then find Nero's speed by dividing the distance he runs by the time he spends running: 24 miles / 3 hours = 8 miles / hour.
So the answer is 8.

Question: Michael loves to paint and sells his creations. He charges $100 for a large painting and $80 for a small painting. At his last art show, he sold 5 large paintings and 8 small paintings. How much did he earn in all?
Answer with step-by-step thinking:
He earned 5 x $100 = $500 for the large painting. And he earned 8 x $80 = $640 for the small paintings. Therefore, he earned a total of $500 + $640 = $1140 in all.
So the answer is 1140.
