Question: Mickey and Johnny are having a contest to see who can run around their block the most. One time around the block equals 200 meters. Johnny runs around the block 4 times. Mickey runs around the block half as many times as Johnny. What is the average distance run by Johnny and Mickey?
Answer: Mickey runs around the block twice because half of 4 is 2. Mickey runs 400 meters in total because 2 times 200 equals 400. Johnny runs 800 meters because 4 times 200 equals 800. In total, they run 1200 meters because 400 plus 800 equals 1200. On average, they run 600 meters because 1200 divided by 2 equals 600. The answer is 600.
[Question]It was reported that 2000 cases of Coronavirus had been confirmed in the state of New York in May 2020. There was half the number of cases in California, which had 400 more cases than the state of Texas. What's the total number of cases that had been confirmed in all of these states?
[Answer]If California had half the number of Coronavirus cases in New York, then the number of cases was 2000 / 2 = 1000 cases. California had 400 more cases than the state of Texas, thus Texas had 1000 - 400 = 600 cases. The total number of Coronavirus cases in all of the three states is 600 + 1000 + 2000 = 3600 cases. The answer is 3600.
Q: Clyde's four children wanted to go see their favorite band perform. The tickets were expensive so Clyde made a deal with his kids. If the average of their scores on their next math test was higher than 89, then he would buy them tickets to the concert.  June earned a 97 on her math test, Patty earned an 85, Josh earned a 100 on his test and Henry earned a 94. What was their average math test score?
A: Together, they scored 97 + 85 + 100 + 94 = 376. There are 4 children so their average math test score is 376 / 4 = 94. The answer is 94.
Question: Danielle wants to make her own popsicles. She finds out she needs popsicle sticks, molds, and juice. She has $10 for supplies. She buys one set of molds for $3 and a pack of 100 popsicle sticks for $1. Each bottle of juice makes 20 popsicles and costs $2. How many popsicle sticks will she be left with if she makes as many as she can?
Answer: She has $6 left after buying initial supplies because 10 - 3 - 1 = 6. She can buy 3 bottles of juice because 6 / 2 = 3. She can make 60 popsicles because 20 x 3 = 60. She has 40 sticks left because 100 - 6 60 = 40. The answer is 40.
