conversations.value: Break down this math problem: A farmer is growing corn. For every 4 seeds he plants, he gets one ear of corn, that he can sell for $.1. It costs $.5 for a bag with 100 seeds. If he makes $40 in profit, how many ears did he sell?

conversations.value: A single seed costs $.005 because .5 / 100 = .005
  It costs $.02 cents to grow an ear of corn because .005 x 4 = .02
  On each ear of corn he makes $.098 profit because .1 - .02 = .08
  He sold 500 ears because 40 / .08 = 500
