conversations.value: Explain how to solve this math problem: 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?

conversations.value: 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.
