Answer:

702.20

Explanation:

Optimal order quantity Q = D+ z σ

Where D is the average demand = 500 units

And σ is the standard deviation of demand = 300

Cu = Cost of stock-out (underestimation) = Selling price – unit cost = $25 -$10 = $15

Co = Cost of excess inventory (overestimation) = Unit cost – Salvage Value = $10 – $5 = $5

Therefore Service level = Cu / (Cu + Co)

= $15/ ($15 + $5)

= 0.75 or 75%

For service level 75% the Z value = 0.674

Therefore, Q = 500+0.674*300 = 702.20
