Expert Solution
Step 1

Annual demand(D) = 4000*2*52 = 4,16,000 units

Unit price = 7000 AED

Ordering cost(S) = 80,000 AED

Holding cost(H) = 25%*7000 = 1750

Calculate EOQ = √((2*D*S)/H)

              EOQ = √((2*4, 16,000*80, 000) /1750)

              EOQ = √38034285.7

             EOQ = 6167.19431 units

Calculate number of orders in a year

Number of order = D/Q

Number of order = 4,16,000/6167.19431

Number of order = 67.45369

Number of order per week = 1.297186
