Answer:
Arrival rate, λ = 4 per hour
Service rate = 1/service time = (1 / 9 minute) * 60 minutes per hour = 20/3 = 6.67 per hour
a) Average number of trucks in system, L = λ/(μ-λ) = 4 / (20/3-4) = 1.5 trucks
b) Average time spent in the system, W = L/λ = 1.5/4 = 0.375 = 0.38 hour
c) Total system cost per day = (2*18 + 75*1.5) *8 = $ 1188 per hour
d) New service rate, μ' = (1/7 minutes) *60 minutes per hour = 8.57 per hour
Average number of trucks in system, L = λ/(μ'-λ) = 4/ (60/7 - 4) = 0.875 = 0.88 trucks
e) Average time spent in the system, W = L/λ = 0.875/4 = 0.2187 = 0.22 hour
f) Total system cost per day = (2*18 + 90*0.88) *8 + 200 = $ 1121.6 = 1122 per day
g) Based on above cost analysis, we see that Total system cost per day is lesser in after the new equipment is installed. Therefore, it is worth to install the new equipment.

I really need this answer as well plz help
Answer:
a. $4,830
b. $2,310
Explanation:
The computation is shown below:
a. The cost of goods sold as on Oct 24 is
Units sold from Oct 1 Inventory is 40 (200 units - 160 units)
And, From Oct. 15 Purchase is 110 (150 units - 40 units)
Now
Cost of goods sold on October 24 is $4,830 (40 × 30) + (110 × 33)
b. The inventory as on Oct 31 is
= (180 - 110) × $33
= $2,310
Answer:
the net operating income is 4.560
Explanation:
Net operating income is a calculation of revenues less cost, minus all reasonably necessary operating expenses. Having said that we can determine that the fixed expenses are included in the necessary operanting expenses unless they include depreciations and amortization. Since the text doesn’t refer to the fixed expenses as depreciations or amortization the calculation is this:
Calculate the cost if the contribution margin is 12%
Cost is equal to = (Revenue*(1-contribution ratio))= (738.000*(1-0.12))= 649.440
Then calculate the net operating income
Net operating income = (Revenue – Cost-operating expenses) = (738.000-649.440-84.000) = 4.560
