According to the United Nations Population Fund (UNFPA), the world reached a population of 7 billion people in late 2011 or early 2012. (a) Suppose that the 149 million square kilometers of land on the surface of the r was divided equally among this population, so that each person was notted a square parcel of land. How long would the sides of each square parcel be? (b) According to the United Nations Food and Agriculture Organization (FAO), only about 32% of the surface of the earth is considered arable and suitable for farming. If only the arable land was divided into equal square parcels among the population, how long would the sides of each square parcel be? C) Express your answers to parts (a) and (b) in terms of some concrete unit of length. For instance, you might compare them to the height of the Empire State Building, the span of the Indianapolis Motor Speedway, or the length of a football field.

Paolo and Van are considering contributing toward the creation of a water fountain. Each can choose whether to contribute $400 to the water fountain or to keep that $400 for a weekend getaway. Since a water fountain is a public good, both Paolo and Van will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.80 of benefit. For example, if both Paolo and Van choose to contribute, then a total of $800 would be contributed to the water fountain. So, Paolo and Van would each receive $640 of benefit from the water fountain, and their combined benefit would be $1,280. This is shown in the upper left cell of the first table. Since a weekend getaway is a private good, if Paolo chooses to spend $400 on a weekend getaway, Paolo would get $400 of benefit from the weekend getaway and Van wouldn't receive any benefit from Paolo's choice. If Paolo still spends $400 on a weekend getaway and Van chooses to…
A nation’s population size and the affluence of its citizenseach influence its resource consumption and environmentalimpact. As of 2013, the world’s population passed 7.1 billion,average per capita income was $11,690 per year, and the latest estimate for the world’s average ecological footprint was2.7 hectares (ha) per person. The sampling of data in the tablewill allow you to explore patterns in how population, affluence,and environmental impact are related. Draw a graph illustrating total impact (on the y axis) inrelation to affluence (on the x axis). What do the resultssuggest to you?
Hubert and Manuel are considering contributing toward the creation of a water fountain. Each can choose whether to contribute $300 to the water fountain or to keep that $300 for a cell phone. Since a water fountain is a public good, both Hubert and Manuel will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.70 of benefit. For example, if both Hubert and Manuel choose to contribute, then a total of $600 would be contributed to the water fountain. So, Hubert and Manuel would each receive $420 of benefit from the water fountain, and their combined benefit would be $840. This is shown in the upper left cell of the first table. Since a cell phone is a private good, if Hubert chooses to spend $300 on a cell phone, Hubert would get $300 of benefit from the cell phone and Manuel wouldn't receive any benefit from Hubert's choice.

Beth and Eleanor are considering contributing toward the creation of a building mural. Each can choose whether to contribute $400 to the building mural or to keep that $400 for a weekend getaway. Since a building mural is a public good, both Beth and Eleanor will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.60 of benefit. For example, if both Beth and Eleanor choose to contribute, then a total of $800 would be contributed to the building mural. So, Beth and Eleanor would each receive $480 of benefit from the building mural, and their combined benefit would be $960. This is shown in the upper left cell of the first table. Since a weekend getaway is a private good, if Beth chooses to spend $400 on a weekend getaway, Beth would get $400 of benefit from the weekend getaway and Eleanor wouldn't receive any benefit from Beth's choice. If Beth still spends $400 on a weekend getaway and…

Suppose that a surfboard designer owns a building and is renting part of the building's space to a doctor. Further suppose that because the surfboard designer is the owner, he has the right to make noise during the day while he sands the boards. While the doctor cannot insist on a quiet environment, the doctor could move to a quieter building. However, rent in the next best building is $400/month more than rent in the noisy building. The surfboard designer can adopt a new technology that eliminates the noise for $325/month. Given this situation, can the doctor find a private solution with the surfboard designer that will make both better off? What is the minimum and maximum payment the doctor would make to the surfboard designer to get the doctor to install the noise-reducing equipment? NOTE: Round your answers to the nearest dollar. Minimum: $ Maximum: $
