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.
Here are a number of examples of variable costs, all in a production setting: 1  Direct materials. 2  Piece rate labor. 3  Production supplies. 4  Billable staff wages. 5  Commissions. 6  Credit card fees. 7  Freight out.
