Answer this question: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 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.

Answer this question:Jeff was driving to the capital city to attend a conference. At first, he was driving at 80 miles/hour for about 6 hours, then the speed limit changed and he had to slow down to 60 miles/hour, and so he drove at this speed for 4 hours. Then he made a stop at a gas station. Once the car was full of gas, he drove at 40 miles/hour the rest of the trip for 2 hours. How many miles did he travel?
In the first stretch he drove 80 miles / hour x 6 hours = 480 miles. In the second stretch he drove 60 miles / hour x 4 hours = 240 miles. After the gas station he drove 40 miles / hour x 2 hours = 80 miles. In total he drove 480 miles + 240 miles + 80 miles = 800 miles.
The answer is 800.

Answer this question:Trevor buys three bouquets of carnations. The first included 9 carnations, and the second included 14 carnations. If the average number of carnations in the bouquets is 12, how many carnations were in the third bouquet?
There are 3 bouquets. The total is the average times the number of bouquets, or 12 * 3 = 36. There are 9 + 14 = 23 accounted for. The third included 36 - 23 = 13 carnations.

Answer this question:Ryan has 40 balls. There are twice as many red balls as blue while the rest are green. If there are 11 blue balls, how many green balls are there?
There are 11 blue x 2 red / blue = 22 red balls. The total number of blue and red balls is 11 blue + 22 red = 33 balls. There are 40 balls - 33 balls = 7 green balls.
The answer is 7.
