conversations.value: Can you give me some step-by-step instructions for this math problem: Wayne wants to serve shrimp cocktail as an appetizer.  He plans on 5 shrimp per guest and will have 40 guests.  If the shrimp costs $17.00 per pound and each pound has 20 shrimp, how much will he spend on the appetizer?

conversations.value: He wants to serve 5 shrimp per guest and will have 40 guests so he needs 5*40 = 200 shrimp
  Each pound of shrimp has 20 shrimp and he needs 200 shrimp so he needs 200/20 = 10 pounds of shrimp
  The shrimp is $17.00 per pound and he needs 10 pounds so he will spend 17*10 = $170.00 on shrimp
