Normally, you grant permissions to a specific assembly. If you have several assemblies, and you are certain that the location is secure, you can grant full trust to the folder where the assemblies are located.

Break Even quantity is the formula that is used to determine the break-even point. Fixed Costs are those normal costs that are necessary to run any business. For example rent, utilities, insurance, and even salaries. Price is the amount usually in dollars that the company will charge for the product.
The reduction in cost per unit is an economy due to scale. Determining the fixed and variable expenses is the first step in performing a break-even analysis. The number of units needed to break even = fixed costs / (price-variable costs per unit). This equation provides a small business owner with a great deal of valuable information by itself, and it can also be changed to answer a number of important questions, like whether a planned expansion will be profitable.
