conversations.value: I'm completely lost with this math problem: Jessica is having a sweet tooth and bought 10 chocolate bars, 10 packs of gummy bears, and 20 bags of chocolate chips. Her total rang up to $150. If the cost of a pack of gummy bears is $2 and a bag of chocolate chips costs $5, how much does 1 chocolate bar cost?
  Can you give me a hand?

conversations.value: The gummy bears cost 10*2=$20.
  The chocolate chips cost 5*20=$100.
  The total cost for these two is 100+20=$120.
  The chocolate bars in total cost 150-120=$30.
  A single chocolate bar costs 30/10=$3.
