And this problem, we're asked to compare two graphs.
00:12
And i'm going to do this over several hours, so i'm going to pick seven hours.
00:17
And first, we'll do 10%, and then we'll do our 20%.
00:25
So at times zero, we have 1 ,000 candies.
00:33
Removing 10%, we would have 1 ,000 minus 0 .1 times 1 ,000.
00:43
Equals 900.
00:47
Here i'll have 1 ,000 minus 0 .2 times 1 ,000 equals 800.
00:58
Okay, and then next i will, that'll be my time 1.
01:04
My time 2 will be 900 minus 0 .1 times 900 equals 810.
01:15
Here i'll have 800 minus 0 .2 times 800 equals 800.
01:26
Oh, my calculator is getting well, minus 0 .2 times 800.
01:32
640.
01:35
Here i'll have 810 minus 0 .1 times 8 .10.
01:48
729.
01:51
I've already done these ones, so let me do my next ones.
01:54
729.
01:56
656, 591.
02:06
And here i've got 591 minus 0 .1 times 591 equals 532.
02:25
So my numbers for my first one are 1 ,900, 810, 729, 656, this, this.
02:37
And i forgot to do this one.
02:49
532 minus 532.
02:53
Times 0 .1.
02:55
479.
02:58
Ok, then up here i'll have 640 minus 0 .2 times 640 is 512.
03:14
Then i have 512 minus 0 .0 or 0 .2 times 512 is 410 minus 0 .2 minus 410.
03:33
Oops, 410 minus 0 .2 times 410.
03:42
328 and 328 minus 0 .2 times 328.
03:52
462 .4, 262 .4, 262 .4 times 0 .2.
04:05
Okay, so now i'm going to go to my next page and prepare a graph...
