/sci/ - Science & Math

I tried doing this algebraically and maybe it's because its 6am and I never went to bed or I'm just a brainlet, but this is as far as I got:
[math]69000(x) = 102000(x - 4) - 80000[/math]

x = 14.8, which is the number of years worked with a bachelors. How would I get it to the 18.8, which would be the actual desired starting point (including tuition), without just adding 4 to x?

Average (mean) Engineering starting salaries:
Bachelors: 69k
Masters: 82k
Doctorate: 102k

If you figure 20k a year for post-bachelors schooling and 4% average pay increases, then it takes about 25 years to break even. Hopefully it's a career you enjoy.
