Answer: (a ) 4 per hour (b ) 4.5 minutes (c ) 3 minutes

Explanation:

Average time between customer arrival = 15 minutes

Average service time = 10 minutes

(a) To calculate the customer arrival rate

Arrival rate = 1 / time between Arrival

= 1 / 15

= 0.066 × 60

= 4 per hour

(b) To calculate the average number of customers in queue

( Arrival time )^2 / service time ( service time - Arrival time)

= (15)^2 / 10 ( 10 - 15)

= 225 / 10 (-5)

= 225 / 50

= 4.5 minutes

(c) To calculate the average time customers spend in the system

Arrival time / service time - Arrival time

= 15 / 10 - 15

= 15/ -5

= 3 minutes

Galina-37 [17]

Answer:

Price elasticity of demand Relation

The Bugatti is very expensive and the result is that very fewer people own it in the world but the Mercedes with an above average price has customers in millions, Honda has more than million customers because it is priced average. So the thing is that the pricing matters in deciding how much of the total customers you want.

kvv77 [185]

Answer:

Premium = $5.76 -$5.51 = 0.25

Percentage of premium = 0.25/5.76 x 100

                                        = 4.34% premium
