Question: A couple agreed to split their expenses equally, including the salary of their house help. While doing her job, the house help had an accident; thus, she underwent a medical procedure which cost her $128. The couple decided to pay half of the medical expenses and the other half will be deducted from her $160 salary. If the husband paid for the entire half of the hospital bill, how much does he still need to pay so that they split the expenses for the house help equally?
Answer with step-by-step thinking: The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48.
So the answer is 48.

Question: Mickey and Johnny are having a contest to see who can run around their block the most. One time around the block equals 200 meters. Johnny runs around the block 4 times. Mickey runs around the block half as many times as Johnny. What is the average distance run by Johnny and Mickey?
Answer with step-by-step thinking: Mickey runs around the block twice because half of 4 is 2. Mickey runs 400 meters in total because 2 times 200 equals 400. Johnny runs 800 meters because 4 times 200 equals 800. In total, they run 1200 meters because 400 plus 800 equals 1200. On average, they run 600 meters because 1200 divided by 2 equals 600.
So the answer is 600.

Question: Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?
Answer with step-by-step thinking:
Elrond was able to get 20 x 2 = 40 tulips. Therefore, the total number of tulips they were able to get is 40 + 20 = 60.
So the answer is 60.
