Many egg producers keep chickens in small cages that do not allow the chickens to move. Some people believe that this is unhealthy, so they buy eggs from chickens that are not caged 24-hours a day. These are sometimes called “free-range” chickens. The United States Department of Agriculture (USDA) allows chickens to be called free-range as long as the chickens spend some of their time outside. The European Union (EU), however, has several additional restrictions. Let's say that one of these is that the farmers must provide enough outside area so that if all the chickens were outside, the density of chickens would be no more than 0.125 chickens/sq meter. A farmer in the United States wants to meet the EU guidelines. She measures her area in yards (1 sq meter = 1.196 sq yards). How many square yards does she need for 3,000 chickens? i. 448.5 square yards ii. 28,379 square yards iii. 28,704 square yards iv. 24,000 square yards
