(a) : Annual demand = 10 packages per day*260 days per year = 2600 packages per year.

H = $1 and S = $10.

Thus Order quantity = (2*2600*10/1) ^0.5 = 228 packages

(b) : Total annual inventory control cost = Q/2*H + D/Q*S

= 228/2*1 + 2600/228*10

= 114 + 114.03

= 228.03

(c) : Yes both annual ordering costs and holding costs are equal at $114.

(d) : In case of order quantity of 100 packages the cost will be = 100/2*1 + 2600/100*10

= 50 + 260

= 310.

Thus the cost figure of $310 in case of 100 packages is more than the cost of $228.03 when 228 packages are ordered. Hence I will recommend that the office manager use the optimal order quantity instead of 100 packages.
