17. Estimated Costs of the Proposed Uniform Estimated Costs of the Proposed Uniform Items Proposed 1 set (HK$) Proposed 100 sets (yds/HK$)Remarks Trousers (a) Fabric cost 32/yd (b) Material cost 83 (2.6 yds/pc)260 yds Advised 300 yds will be produced in case fabric is insufficient to meet needs due to defect/fade during fabric moisture transfer treatment. (c) Workmanship 75 Total Cost (b+c) 158 T-Shirt (a) Fabric cost 34/yd (b) Material cost 40.8 (1.2 yds/pc)120 yds The calculation for pc is loose and it is not necessary to more yds than 120 yds (c) Workmanship 36 Total Cost (b+c) 90.8 Total Set Cost236.8 100 Set Cost23680Total Cost 23680+1280 (40 more yds)=22400 HK$ Remarks: other expenditure includes carriage, MMT treatment
