1. Math model: employee gives company $100 for purchase; company gives employee $100 for salary. Both have $0 saving. If one takes $100 and gives $80; the other loses $20 ; while one gains $20.
1. 數學模型:員工給公司100美元購買; 公司給員工100美元的工資。 兩者都節省了0美元。 如果一個人拿100美元並給80美元; 另一個損失20美元; 而一個人獲得20美元。
2. Money $100 salary, spending $80, so spending is less than salary. For companies to profit, hire 2 ( 2x$100) Income is $80 x3; 1 person is unemployed.
