Thought this might be of some interest, so, posting it here. ^^
DEFINITION OF PROBLEM:
----------------------------------
Scenario:
I) You want to work x hours per week.
II) You want to keep commuting (ie. travel) to a minimum.
III) You want to maximize your earnings.
PROBLEM:
What is minimum pay-rate that a job that requires commuting have so that it's worth-while (from a fiscal and temporal standpoint) for you to bother commuting there?
BACKGROUND:
While some jobs can be found downtown that pay a higher than minimum wage, you may actually be able to earn more by staying around your local neighborhood, working at a minimum-wage job, than you would if you worked at the higher paying job.
Consider:
i) Commuting to your workplace can take a considerable amount of time per week.
ii) Although the wage-rages would be different, you would be working the same amount of hours if you were working locally vs at a remote location.
iii) Compare what your net weekly earnings at your local job would be if you worked extra hours there equivalent to the sum of the weekly hours commuting you would waste whilst traveling to your higher wage job.
SOLUTION:
Let p = pay-rate at local job. ($/h)
Let P = pay-rate at remote job. ($/h)
Let t = time spent commuting per week. (h)
Let x = hours worked per week. (h)
Let b = cost of transportation per week. ($)
Equation as follows:
P>=p(t/x + 1) + b/x
EXAMPLE:
-------------------
-- You currently work 18 hours/week at minimum wage ($9.50/h), 3 days a week, within walking distance to your house.
-- Your commuting time is less than 15 minutes by foot hence we assume it is effectively zero.
-- You are aware of a job downtown that pays $12/h . OC Transpo planner tells you commuting time one-way equals 1 h . Let's say you use bus tickets. Each bus ticket costs $1.15. You need 4 tickets per day to travel; 2 to get to work and 2 to get back.
-- Your weekly cost of transport will then be 4x(cost of ticket)x(number of days worked)=$13.80 fare
P>=9.5(6/18+1)+13.8/18
>=$13.43...
For this example, at 18 h/week, it is only worth your while to travel downtown if you are getting paid more than $13.43/h .
(Note: An interesting observation is that the more hours you work per week, the less the minimum wage can be to make it worth while. Eg. If you worked 30 h/week (ie. 3 8h-days), you'd need a pay of at least $11.86/h ! Hence, whether it's worthwhile really depends on how many hours you work per week! ;3 )
Supper time now!
