Thus average fixed cost is the fixed cost per unit of output. Suppose for a firm the total fixed cost is Rs. 2,000 when output is 100 units, average fixed cost (AFC) will be Rs. 2,000/100 = Rs. 20 and when output is expanded to 200 units, average fixed cost will be Rs. 2,000/200 = Rs.
On July 3, 1886, mechanical engineer Karl Benz drove the first automobile in Mannheim, Germany, reaching a top speed of 16 km/h (10 mph). The automobile was powered by a 0.75-hp one-cylinder four-stroke gasoline engine.
