Many academic institutions offer a sabbatical policy. Every seventh year a professor is given a year free of teaching and other administrative responsibilities at full pay. For a professor earning $70,000 per year who works for a total of 42 years, what is the present value of the amount she will earn while on sabbatical if the interest rate is 6% (EAR)? Note: Assume that the sabbatical annual salary is paid in one lump sum every 7 years.

$1,26,964.34

Explanation:

As per the given question the solution of present value is provided below:-

To find out the present value first we need to calculate the interest rate

Interest rate                  6%  

Number of Years           7  

Employment years          42  

Number of sabbaticals    6 NPER

(7 year - 1 year)

Interest rate periodic       0.503630259 RATE  (=1.06^7-1)

Salary                               70000  PMT

Present value                   $1,26,964.34 =PV(rate,nper,Pmt)

To reach at present value we simply put the values into formula.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
