Question: Janice adds 2 tablespoons of koolaid power and 16 tablespoons of water to a jug. She leaves it out long enough for 4 tablespoons of water to evaporate. Then she quadruples the amount of water in the jug. What percentage of the liquid in the jug is koolaid powder?
Answer: Step-by-step reasoning process: First find how many tablespoons of water are left after the evaporation: 16 tbs - 4 tbs = 12 tbs. Then multiply this number by 4 to find how much water is in the jug after Janice refills it: 12 tbs * 4 = 48 tbs. Now add the 2 tablespoons of koolaid powder to find the total volume of the liquid in the jug: 48 tbs + 2 tbs = 50 tbs. Now divide the volume of the koolaid powder by the total volume and multiply by 100% to find the percentage of the liquid that's koolaid: 2 tbs / 50 tbs * 100% = 4%.
So the answer is 4.

Question: In 3 years, Jayden will be half of Ernesto's age. If Ernesto is 11 years old, how many years old is Jayden now?

Question: Hannah comes home from work to find her older son taped her younger son to a chair with 22 strands of duct tape. If Hannah can cut 8 strands per minute and her son can cut 3 strands per minute, how long will it take them to free her younger son?
Answer: Step-by-step reasoning process: First find the total number of strands the two of them can cut per minute: 8 strands + 3 strands = 11 strands. Then divide the total number of strands by the number of strands they cut per minute to find the number of minutes it takes to cut all the strands: 22 strands / 11 strands / minute = 2 minutes.
So the answer is 2.

Question: The Diving Club offers 2 beginning diving classes on weekdays and 4 beginning classes on each day of the weekend. Each class has room for 5 people. How many people can take classes in 3 weeks?
Answer:
Step-by-step reasoning process: There are 2 classes x 5 days = 10 classes on weekdays. There are 4 classes x 2 days = 8 classes on weekends. There are a total of 10 + 8 = 18 classes per week. So each week, 18 x 5 = 90 people can take classes. Thus, 90 x 3 = 270 people can take classes in 3 weeks.
So the answer is 270.
