00:00:00.340 --> 00:00:02.799 A:middle L:90%
it's there. So when you right here. So
2
00:00:02.799 --> 00:00:12.099 A:middle L:90%
we're gonna use the pft equation to get 10,000 all
3
00:00:12.099 --> 00:00:29.000 A:middle L:90%
over one plus 10,000 minus 1000 over 1000 times eats
4
00:00:29.000 --> 00:00:35.850 A:middle L:90%
and negative Katie. Then we just simplify to get
5
00:00:35.850 --> 00:00:43.659 A:middle L:90%
10,000 all over one plus nine e negative, Katie
6
00:00:47.439 --> 00:00:53.420 A:middle L:90%
. Then we just made this equal 2 2500 when
7
00:00:53.420 --> 00:00:56.429 A:middle L:90%
it's p of one. So we know that this
8
00:00:56.439 --> 00:01:02.210 A:middle L:90%
is gonna be equal to one two. You get
9
00:01:02.210 --> 00:01:10.140 A:middle L:90%
2500 times one plus nine e to the negative K
10
00:01:10.159 --> 00:01:18.340 A:middle L:90%
this equal to 10,000 and we get nine e to
11
00:01:18.349 --> 00:01:25.049 A:middle L:90%
the negative. K is equal to three and we
12
00:01:25.049 --> 00:01:27.290 A:middle L:90%
get e to the negative. K is equal to
13
00:01:27.290 --> 00:01:33.549 A:middle L:90%
1/3. We take the Ellen of both sides,
14
00:01:34.239 --> 00:01:38.549 A:middle L:90%
then we get negative. Cake is equal to out
15
00:01:38.560 --> 00:01:45.569 A:middle L:90%
on of 1/3 when we plug in p A four
16
00:01:48.719 --> 00:01:51.540 A:middle L:90%
. Since this asking for three years out for the
17
00:01:51.540 --> 00:02:00.829 A:middle L:90%
first year, we get 10,000 over one plus nine
18
00:02:00.840 --> 00:02:07.030 A:middle L:90%
e toe l n of 1/3 terms for and we
19
00:02:07.030 --> 00:02:07.349 A:middle L:90%
got 9000
