Question 1038925: Did you know that South Korea has some of the fastest Internet in the world? That's great if you live in a big city like Seoul, but what if you live somewhere else?
[The scene changes to show a lush green field with a river running through it. The screen pans up to show more fields and mountains.] Many small towns and rural businesses still do not have Internet or even basic telephone access! Remoteness, mountains, islands, and other geographic features make it too expensive for communication companies to reach the few people still living far from the city.
[The image changes to show clouds in the sky and then two women sitting and looking at a laptop.] My friend Uyen and I are helping a rural community write a grant to bring affordable wireless Internet to their village.
We're asking the United Nations for $50,000 to build cell towers in and around the area. But what percentage of the community will actually be served by the grant? [The image of the clouds in the sky reappears and then three metal cellular towers rise up and start transmitting.]
[An image of a person standing and talking on the phone in a room filled with computer servers with wires is shown.] We've talked to Internet providers. They have a formula for the cost of bringing "digital communication infrastructure" (cell phone towers) into a new community. Here it is: [The image changes to show a field with two cell phones sitting on the dirt and "C equals parentheses, 25,000 times p, parentheses, over, parentheses, 100 minus p, parentheses, 0 is less than or equal to p, is less than 100"] is shown on-screen.
Where C is the cost in dollars for supplying p percent of the population with Internet.
Uyen did a quick calculation for the cost of reaching 10% of the community:
C equals parentheses, 25,000 times p, parentheses, over, parentheses, 100 minus p, parentheses, 0 is less than or equal to p, is less than 100, C equals parentheses, 25,000 times 10, parentheses, over, parentheses, 100 minus p, parentheses, 250,000 over 90, equals $2777.77
She reasons that if it costs $2777.77 to reach 10% of the community, then to reach 100%, it should cost 10 times that much: ["$2777.77 times 10 equals $27,777.77 equals everyone!"] is shown on-screen.
[The image changes to show a forested area with a creek flowing through it and a path. A sign that says "You are now in a WiFi Area" is shown.]
But I'm not sure. I think there is something about the formula that will affect our proposal.
Is Uyen correct in thinking that $27,777 will be enough to reach the whole community? Is our grant proposal of $50,000 reasonable? does uyens make sence why or why not?
