Cutting in new trench drains is nasty work. Much easier if there is no floor to begin with. For what it's worth, this is the trench drain system that we have planned: http://www.watts.com/pages/_products...=67&parCat=108 Click the Dead Level D link. It's expensive but saves a ton of labour in installation.
(Total fixed costs + Total variable costs) / Total units produced. The cost per unit should decline as the number of units produced increases, primarily because the total fixed costs will be spread over a larger number of units (subject to the step costing issue noted above).Thus, the cost per unit is not constant.For example, ABC Company has total variable costs of $50,000 and total fixed costs of $30,000 in May, which it incurred while producing 10,000 widgets. The cost per unit is: ($30,000 Fixed costs + $50,000 variable costs) / 10,000 units = $8 cost per unit.hus, the cost per unit is not constant.

Cost per Piece. The cost of each individual piece, after you click the Calculate Now button. This is simply the cost of the unit divided by the number of pieces in the unit. For example, if a unit (carton) of candy bars costs $10.00 and contains 10 candy bars, the Cost per Piece is $1.00.et Cost per Piece. The Net Cost of each piece in your unit. The Net Cost is the sum of the Cost per Piece and the Shipping Cost per Piece. For example, if the Cost per Piece of an item is 1.00 and the Shipping Cost per Piece is $0.10 then the Net Cost per Piece is $1.10.
