Transcript

00:08 Okay, we're asked to consider a candy jar and we're told that it contains a thousand candies.

00:13 We walk past once per hour.

00:16 We take 10 % each trip and that is candies remaining.

00:35 We just got told we had to print so my printing is worse than my writing, so i apologize.

00:41 So what we're going to do is trip one.

00:45 At time zero, there are 1 ,000 candies.

00:49 At time one, at time two hours, times three hours, times four hours, times five hours, times six hours.

01:01 We take 10 percent candy, sketch a number of candies for a few hours.

01:08 Okay, so we'll have, we 10 percent equals 100, so we'll have 900 candies remaining.

01:21 And let me do that by doing 1 ,000 minus 100.

01:28 Equals 900.

01:30 So then we have 900 minus 0 .1 times 900 will equal 800 to 10.

01:42 Then i'll have 810 minus 0 .1 times 810.

01:48 Oh, let me get my calculator open here.

01:55 Okay, still calculating.

01:57 Okay, 900 minus is 810.

02:03 And then 800 minus.

02:09 That'll be 729 and then 729 minus 0 .1 times 729 .6 .6 and minus this will be 591 and then i think this is the that's 0 1 2 3 4 5 .5 and 6 will be 591 minus 531...
