conversations.value: Hannah wanted to make an apple pie that would serve 8 people.  She needed 2 pounds of apples that were on sale for $2.00 per pound. The pre-made pie crust cost $2.00.  The lemon cost $.50 and the butter cost $1.50.  How much did each serving of pie cost?

conversations.value: 2 pounds of apples at $2.00/pound would cost 2*2 = $4.00
  If we add all of the purchases together then the total bill was 4+2+.50+1.50 = $8.00
  There are 8 servings per pie. So $8.00/8 servings = $1.00 per serving
