<human>:  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?
<bot>: How many shrimp will he need? ** He wants to serve 5 shrimp per guest and will have 40 guests so he needs 5*40 = <<5*40=200>>200 shrimp
How many pounds of shrimp will he need? ** Each pound of shrimp has 20 shrimp and he needs 200 shrimp so he needs 200/20 = <<200/20=10>>10 pounds of shrimp
How much will he spend on the appetizer? ** The shrimp is $17.00 per pound and he needs 10 pounds so he will spend 17*10 = $<<17*10=170.00>>170.00 on shrimp
