Stream of consciousness rationale: 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%.
The question and answer pair are described below.
Q: 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?
A: 4
