conversations.value: Solve the following math problem: Jame gets a raise to $20 per hour and works 40 hours a week.  His old job was $16 an hour for 25 hours per week.  How much more money does he make per year in his new job than the old job if he works 52 weeks a year?

conversations.value: He makes 20*40=$800 per week
  He used to make 16*25=$400 per week
  So his raise was 800-400=$400 per week
  So he makes 400*52=$20,800 per year more
