Millerstown, on the Nolin River, was the first community to be formally incorporated in 1826; Falls of Rough grew up around the Green Sawmill, which first operated in 1823; and Grayson Springs, a popular summer resort, opened in 1830 and peaked in prosperity about 1900.
Example 1. Assume a business produces clothing. A variable cost of this product would be the direct material, i.e., cloth, and the direct labor. If it takes one laborer 6 yards of cloth and 8 hours to make a shirt, then the cost of labor and cloth increases if two shirts are produced.
Variable Costs: Variable costs are costs that change with the amount of work. Examples of variable costs are hourly labor, the cost of material, the cost of supply, fuel for bulldozer etc. Direct Costs: Direct costs are expenses that are billed directly to the project. Examples of direct costs are team travel expenses, team wages, the cost of material used in a project, costs incurred for recognition and awards materials used to construct a building.
