In 2012 there was a contest to see who could get the 25 billionth app on the Apple App Store. My teacher, Mr. Oldfield challenged us to try and see when the App Store would hit 25 billion downloads. First I looked on the website http://threeacts.mrmeyer.com/25billionapps/ and figured out how many downloads happened per minute. And to do that I just looked on his website and he had screenshots taken every minute of the number of downloads that were happening. I wrote down screenshots recorded at 6:27, 6:28, 6:29, and 6:30. I then added the numbers that I recorded for each time and divided them by 4. The answer that I got was average per minute. Then I took 25 billion and subtracted it by my last screenshot recorded, ( this is the downloads left until 25 billion.) I then took the hour per minute which is 9,974 and divided it by 60, because there is 60 minutes in an hour. After I did the math I got about 166 hours. And then I took 166 and divided it by 24, because there is 24 hours in a day. The quotient that I got was about 7 days. So I added seven days to the day February 24 ( that is the date that Dan Meyer took the screenshots on his computer.) I had to keep in mind that 2012 was a leap year (the year that the contest was held.) If the downloading of apps stayed at a constant rate the contest would be over on March 2nd around 6:00 PM. I think that the number would increase as the number of downloads got closer to 25 billion. So I would start to download apps around 3:30 PM.
