Answer:
The rate of interest is 11.111%
The Deposit should be $90 today.
The future value at the end of this year will be $100.
Explanation:
Future value of $100
Present value of $100 at 11.111% = $100/11.111 = $90
The future value of a deposit today is the value after a period of one year or so periods. The rate of interest produces the discount factor that can calculate the present value of $100. To make a one-time deposit of $90 today will increase in value to $100 using an interest rate of 11.111%.
