conversations.value: Break down this math problem: Every time Carl earned $0.50 he would go to the corner market and buy a candy bar.  Carl's neighbor said he would pay him $0.75 every week for taking out his trash.  At the end of four weeks, how many candy bars will Carl be able to buy?

conversations.value: He is paid $0.75 every week for 4 weeks, so Carl made .75 * 4 = $3.00 in 4 weeks
  Each candy bar cost $0.50 and he made $3.00 so 3.00/.50 = 6 candy bars
