Elsie has a specific amount of wet wipes in a container in the morning. Throughout the day, she refills the container with 10 more wipes after using up 20. By nighttime, she only has 60 wipes left. How many wipes were in the container in the morning?
Let's think: Let w be the number of wet wipes Elsie had in the morning. Throughout the day, she used w - 20 wet wipes. Once that happened, she had to refill the container resulting in w - 20 + 10 = w - 10 wet wipes. By nighttime, she had w - 10 = 60 wipes. So then, w = 60 + 10 = 70. She started with w = 70 wipes.. The answer is: 70.

James and Ali together own $250. If you know that James owns $40 more than Ali, then calculate the amount owned by James.
Let's think: Let X be the amount owned by James. The amount owned by Ali is X - $40. The total amount owned by both of them X + (X - $40) = $250. Combining like terms, we get X * 2 - $40 = $250. Adding $40 to both sides, we get X * 2 = $290. Dividing both sides by 2, we get X = $145.. The answer is: 145.

The students at Evelyn's school are keeping journals. They have 3 journal-writing sessions per week. Each student writes 4 pages in each session. How many journal pages will each student write in 6 weeks?
Let's think: In a week, a student writes 3 * 4 = 12 pages. So in 6 weeks, each student will write 12 * 6 = 72 pages.. The answer is: 72.

Jesse and Mia are competing in a week long race. They have one week to run 30 miles. On the first three days Jesse averages (2/3) of a mile. On day four she runs 10 miles. Mia averages 3 miles a day over the first 4 days. What is the average of their average that they have to run over the final three days?
Let's think:
Jesse runs 2 miles in the first three days because 3 x (2 / 3) = 2. Jesse has 18 miles left to run because 30 - 10 - 2 = 18. Jesse has to run an average of 6 miles a day because 18 / 3 = 6. Mia runs 12 miles over the first four days because 4 x 3 = 12. She has 18 miles left to run because 30 - 12 = 18. She has to run six miles a day because 18 / 3 = 6. The total they both have to run is 12 miles a day. The average they have to run per day on average is 6 miles because 12 / 2 = 6.. The answer is: 6.
