Q: A water tank has a capacity of 4000 gallons. Mack connects a pipe to the tank that fills the tank with water at the rate of 10 gallons per hour. How long will it take to fill the tank to 3/4 of its capacity?
A: 3 / 4 of the water tank is 3 / 4 * 4000 = 3000. If the pipe fills the tank with water at the rate of 10 gallons per hour, it will take 3000 / 10 = 300 hours to fill the tank to 3 / 4 of its capacity. The answer is 300.
Question: Matt spends 80 minutes washing the outside of his car and 1/4 that amount of time cleaning the inside. How long does he spend cleaning his car total?
Answer: First find the time Matt spends cleaning the inside of his car: 80 minutes / 4 = 20 minutes. Then add that time to the time he spends cleaning the outside to find his total cleaning time: 20 minutes + 80 minutes = 100 minutes. The answer is 100.
[Question]Two teams are playing in a stadium with a capacity of 2000 people. The total number of people in the stadium is 3/4 of the total capacity and each person paid $20 in entry fees. What is the difference between the total amount of fees collected when the stadium was 3/4 full and if the stadium would have been full?
[Answer]When the stadium is full, the total fees charged is 2000 * $20 = $40000. When the stadium is 3 / 4 full, the total number of people in is 3 / 4 * 2000 = 1500 people. The total entry fees collected when the stadium is 3 / 4 full is 1500 * $20 = $30000. The difference in the total entry fees when the stadium is full and when it's 3 / 4 full is $40000 - $30000 = $10000. The answer is 10000.
