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.
A good example of a variable cost is materials. If one pair of pants requires $10 of fabric, then every pair of pants requires $10 of fabric, no matter how many pairs are made. The fabric cost is $10 per unit at every level of production. If one pair is made, the total fabric cost is $10; if two pairs are made, the total fabric cost is $20; and if 1,000 pairs are made, the total fabric cost is $10,000. Hence, the total cost is increasing and linear in the production level. Fixed Costs:
