10 years

Step-by-step explanation:

Given : James has a job with a current salary of $42,000. He wants to earn a college degree that will take him 2 years to complete and it will cost $28,000 per year. He will go to school full time and will not be able to work. Upon graduation, James' new salary will be $56,000 per year

To Find: How many years will it take James to recover his investment?

Since it will take two years to complete his degree

Fees of one year = $28000

Fees for two years = 28000*2 =56000

since he was earning $42000 per year

so, total earning he is losing in these two years = $84000

since she is paying 54000 for two years.

So, total amount she is losing = $84000+$56000 = $140000

So, total amount she needs to recover is $140000

After graduation, James' new salary will be $56,000 per year.

His previous salary was $42,000

So, profit he is earning = $56,000 -$42,000= $14000

Now,  years will it take James to recover his investment = 140000/14000 =10

Hence it take 10 years to recover his investment
