Question: If eight liters is 20% the capacity of a container filled with water, calculate the total capacity of 40 such containers filled with water.
Answer: If eight liters is 20% the capacity of a container filled with water, when the container is full, which is 100%, the container will contain 100% / 20% * 8 liters = 40 liters. The total capacity of 40 such containers filled with water is 40 * 40 = 1600 liters. The answer is 1600.

Q: Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?
A: Kiki spends 60 / 100 * $90 = $54 of her money on hats. The amount she spends on buying scarves is $90 - $54 = $36. If each scarf is sold at $2, Kiki will buy $36 / $2 = 18 scarves. The answer is 18.
Question: A camping site recorded a total of 150 campers for the past three weeks. Two weeks ago, there were 40 campers which was 10 more than the number of campers three weeks ago. How many campers were there last week?
