Utilization Average time a customer spends in the system

rho = λ/μ w = 1/μ - λ = L/λ

Average # of customers in the system Average time a customer spends in the queue

Ls = λ/μ - λ Wq = λ/μ(μ - λ) = Ls/λ

I've seen one like this could this be what your talking about

b you would need to multiply 24 by 3 to get 72 cups. you would also need to multiply 18 by 4 to get 72 napkins. so you would need 4 napkin packages and 3 cup packages.
