For this problem number 107.
00:03
Okay, so if you're given $2 ,000 of the first year, and then the management gave you three options.
00:20
Okay, so for option one, a bonus of $100 ,000 each year.
00:26
So you will have, you'll have $2 million plus times seven.
00:45
Okay, so which you have $2 ,070 ,000 after seven years.
00:57
Okay, so for option two, you will have an annual increase of 4 .5 % per year after the first year.
01:26
So you will have, the first year is 2 million, and the second year is 2 million times 1 plus 4 .5.
01:39
Okay, and the third year will be 2 million times 1 .045 to the second, okay.
02:00
So we know this is a geometric sequence and a1 is 2 million and we know that r equals to 1 .05.
02:15
So let's calculate it.
02:17
So we have s equals to a1 times 1 minus 1.
02:38
To the 6, okay, over 1 minus 1 .045.
02:48
So this equals to, okay, so this will give you 13 million, $4 ,303 ,783 .33.

After seven years...
