conversations.value: I'm completely lost with this math problem: A normal lemon tree produces 60 lemons per year.  Jim has specially engineered lemon trees that produce 50% more lemons per year.  He has a grove that is 50 trees by 30 trees.  How many lemons does he produce in 5 years?
  Can you give me a hand?

conversations.value: Each tree produces 60*.5=30 more lemons than normal
  So they each produce 60+30=90 lemons
  He has 50*30=1500 trees
  So every year he produces 1500*90=135000 lemons
  That means he produces 135000*5=675,000
