Suppose that,

c_t = Net number of drivers hired at the beginning of the year t.

h_t = Number of drivers hired at the beginning of the year t.

f_t = Number of driver fired at the beginning of the year t.

d_t = Number of drivers have been hired or fired at the beginning of the year t.

z = Cost of the company

Now, the cost of the company due to salary, hiring and firing at the beginning of the first year

d₁ = 50+h₁-f₁

at the beginning of the second year, there were d₁ drivers.

Therefore, number of drivers after hiring or firing at the beginning of second year

d₂ = d₁+h₂-f₂

Similarly,

d₃ = d₂+h₃-f₃

d₄ = d₃+h₄-f₄

d₅ = d₄+h₅-f₅

Also, the number of the ...
