Step-by-step reasoning process: Linda wants to do two coats, so the total area she will be painting is 2 coats * 600 sq. ft. / coat = 1200 sq. ft. A gallon of paint will cover 400 sq. ft., so Linda will need 1200 sq. ft. / 400 sq. ft. per can = 3 cans of paint.
[Q & A] The question is Linda is repainting her bedroom. The wall area is 600 sq. ft. If a gallon of paint can cover 400 sq. ft., how many gallon cans of paint will Linda have to buy if she wants to do two coats?
The answer is 3

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%.
[Q & A] The question is 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?
The answer is 4

Step-by-step reasoning process: One pizza costs twice as much as the burger, which means 9 * 2 = $18. Three burgers would cost 9 * 3 = $27. So one pizza and three burgers would cost in total 18 + 27 = $45.
[Q & A] The question is In a restaurant, a burger costs $9, and a pizza twice as much. How much would cost one pizza and three burgers?
The answer is 45
