conversations.value: Provide a step by step solution for the following math problem: For every loaf of bread that Ted buys, he needs an additional 2 packs of sandwich meat and 2 packs of sliced cheese to make 10 sandwiches.  The bread costs $4.00, the sandwich meat costs $5.00 per pack and the cheese costs $4.00 per pack.  He has a $1.00 off  coupon for one pack of cheese and an additional $1.00 coupon for one pack of meat.  How much does each sandwich cost?

conversations.value: He buys 2 packs of sandwich meat at $5.00 a pack so 2*5.00 = $10.00
  He buys 2 packs of cheese at $4.00 a pack so 2*4.00 = $8.00
  The loaf of bread cost $4.00 plus $10.00 for meat and $8.00 for cheese so his total is 4+10+8 = $22.00
  He has coupons to use a checkout so his new total is 22-1-1 = $20.00
  He can make 10 sandwiches from his purchase and his purchase total is $20 so 20/10 = $2.00
