Answer #1

Average demand

250/Week

Lead time

3 Weeks

Order cost

575/ Order

Unit cost

$21.50

Carrying charge rate

0,20

Number of weeks per year

52

Economic order quantity = square root of [(2 x demand x ordering costs) ÷ carrying costs]

Q= Square Root of ((2 x 250 x 575) / 0.20)

EOQ = 1198.96

Reorder Pont – (Average daily unit sales x Delivery Lead Time) + Safety Stock

Average daily unit sales = 250/7 = 35.71

Delivery Lead Time = 3 Weeks

Safety Stock = 250/ Week

                     = (35.71 x 3) + 250

Reorder quantity = 357.13
