Answer:

The average time spent waiting in line for each student is 2.25 students.

Explanation:

Use Lq with a single server formula.

λ = Avg arrival rate  = 15 std/hr

μ= Avg server rate (individual server capacity) = 20 std/hr

Μ = # of servers/line (identical capacities)

= λ^{2}/μ(μ- λ)

=15^{2} / 20(20-15)

= 225/100

=2.25 students.

MrRissso [65]

Answer:

a. 4 years

b. 5 years

Explanation:

The payback period is the time taken for the cash inflows from an investment to equal to the initial cash outflow or amount invested. To get this, the cash inflow are deducted from the outflows until the net is zero.

Considering both expected cash flows (all amounts in $);

Period    Initial out flow   Inflow         Balance         Inflow         Balance

Year 0    (1,200,000)              0          (1,200,000)       0            (1,200,000)      

Year 1                             300,000       (900,000)    150,000     (1,050,000)

Year 2                            300,000       (600,000)    150,000     (1,050,000)

Year 3                            300,000       (300,000)    400,000     (1,050,000)  

Year 4                            300,000               0           400,000     (1,050,000)  

Year 5                                                                        100,000     (1,050,000)

From the table above, with an inflow of $300,000 yearly, the inflows would equal the total outflow in 4 years while the annual cash flows: $150,000, $150,000, $400,000, $400,000, and $100,000 would make the inflows equal to the outflows in 5 years.
