Hello.
00:03
Let's find the answer which apartment you should rent comparing the total costs for all these four different locations.
00:17
So we just, for simplicity as is given, we assume rent and the opportunity cost of your time.
00:24
Commuting to work are the only factors influencing the location in which you will rent.
00:32
Your apartment.
00:34
Okay, let's look at all four options.
00:40
Let's start with location a.
00:44
For location a, you don't spend any time going to work, right? there is no need to go anywhere because this location is in the city where your job is.
01:03
So we have zero times and zero minutes.
01:09
So answer option a is zero.
01:14
It's about time.
01:16
Let's look to the location b.
01:19
Now you need to spend 10 minutes more from your job than location a.
01:26
So 10 minutes and since you have a round trip, you spend 20 minutes every day.
01:36
We multiply this by 21 because you work 21.
01:42
Days per month and you value your time as $22 per hour.
01:53
This will be your monthly cost of $22 per hour.
02:09
And 20 minutes it will be maybe we can for simplicity we can write it like hours.
02:17
20 minutes is one third of hour...
