To find : the principal P.
Answer to Problem 13E
The initial investment is
Explanation of Solution
Given information : Amount available for retirement is $500,000, rate of interest is 5% and duration of investment is 10 years
Concept Involved:
Solving for a variable means getting the variable alone in one side of the equation by undoing whatever operation is done to it.
Formula Used:
For periodic compounding, after t years, the balance A in an account with principal P, number of times interest applied per time period n and annual interest rate r (in decimal form) is given by the formula:
Calculation:
Description | Steps |
Substitute the given information in the formula | |
Use symmetric property of equality which states that if a = b then b = a to rewrite the equation | |
Simplifying the left side of the equation |
Calculation (Continued):
Description | Steps |
Divide by | |
Simplify fraction on both sides |
Conclusion:
The principal $303581 should be invested at rate of 5%, compounded monthly, so that $500,000 will be available for retirement in 10 years
