conversations.value: Break down this math problem: Abraham owns 80 square meters of unused land. He sold half of the land for $50, and after a month, he sold another 1/4 of his land for $30. He then sold the remaining land for $3 per square meter. How much money will he be able to earn after selling all his unused land?

conversations.value: Abraham sold 1/2 x 80= 40 square meters of his unused land.
  After a month, he sold 1/4 x 40 = 10 square meters of his land.
  So, the total land he already sold is 40+10= 50 square meters of his land.
  He has 80 - 50 = 30 remaining land to be sold at $3 per square meter.
  So he earned $3 x 30 = $90 for that land.
  Therefore, he earned a total of $50 + $30 + $90 = $170.
