conversations.value: Michael ran a bakeshop and had to fill an order for 5 peach pies, 4 apple pies and 3 blueberry pies.  Each pie recipe called for 3 pounds of fruit each.  At the market, produce was on sale for $1.00 per pound for both blueberries and apples.  The peaches each cost $2.00 per pound.  How much will Michael spend at the market buying the fruit for his pie order?
conversations.from: assistant
conversations.value: Each pie needs 3 pounds of fruit so for 5 Peach pies, 3*5=15 pounds of fruit
  3 pounds of fruit for 4 apple pies is 3*4 = 12 pounds
  3 pounds of fruit for 3 blueberry pies is 3*3 = 9 pounds
  He needs 12 pounds of apples and 9 pounds of blueberries so 12+9 = 21
  21 pounds of fruit at $1.00 per pound is 21*1 = $21.00
  15 pounds of peaches will cost $2.00 per pound so 15*2 = $30
  The apple and blueberries will cost $21.00 and the peaches will cost $30 so 21+30 = $51
