Here is the info I have for the problem I need to solve:
You have two investment opportunities. One will have a 10% rate of return on an investment of $500; the other will have an 11% rate of return on a principal of $700.
You would like to take an advantage of the higher yield investment but have only $500 available.
What is the maximum rate of return that you would pay to borrow the $200
need to take advantage of the high yield investment?
The expert solves the rate of return with excel.
