given james has a job with a current salary of $42,000. he wants to earn a college degree that will take 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. how many years will it take james to recover investment?
the current salary of james is $42,000. so for 2 years he will earn 42,000 x 2 = 84000.
for one year the cost of education is $28,000. therefore for 2 years it will be $56000.
the sum will be 84,000 + 56,000 = 1,40,000.
by dividing $1,40,000/$56,000 we get 2.5 years.
james will take 2.5 years to recover investment.
