conversations.value: Please show me the solution for: Barbara asked the butcher for 4 1/2 pound steaks that cost $15.00/pound.  She also asked for a pound and half of chicken breasts that were $8.00 a pound.  How much did she spend at the butchers?
conversations.from: assistant
conversations.value: She ordered 4 1/2 pound steaks so that's 4*.5 = 2 pounds of steak.
  The steak cost $15.00 a pound and she bought 2 pounds so that's 15*2 = $30.00 for 4 steaks.
  She also needed 1.5 pounds of chicken breasts at $8.00 a pound so that's 1.5*8 = $12.00 for chicken.
  The steaks cost $30.00 and the chicken cost $12.00 for a total of 30+12 = $42.00 spent at the butchers.
