conversations.value: I would love to understand how to solve this problem: Alvin owns coconut trees that yield 5 coconuts each. If a coconut can be sold for $3 and Alvin needs $90, how many coconut trees does he have to harvest?
  Can you explain?

conversations.value: Alvin needs to harvest 90/3= 30 coconuts to earn $90.
  Therefore, the total number of trees that he has to harvest is 30/5= 6.
