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.
Examples of variable costs are sales commissions, direct labor costs, cost of raw materials used in production, and utility costs. The formula for variable cost is given as: Total variable cost = Quantity of output x Variable cost per unit of output. Variable Cost Example For example, letâs assume that it costs a bakery $15.00 to bake a cake - $5.00 for raw materials such as sugar, milk, and flour, and $10.00 for the direct labor involved in baking 1 cake.
