Final answer:
To determine how much Mr. E needs to invest now to have $200,000 in 5 years with a 6.5% interest rate compounded semi-annually, the compound interest formula is applied and results in an initial investment amount of $145,946.33.
Step-by-step explanation:
Mr. E wants to have $200,000 in 5 years for his retirement with an investment that earns 6.5% interest compounded semi-annually. To find out how much he needs to invest now, we will use the formula for compound interest:
P = A / (1 + r/n)^(nt)
Where:
- P is the principal amount (the initial amount of money)
- A is the future value of the investment/loan, including interest
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per year
- t is the number of years the money is invested/borrowed for
In this case, A = $200,000, r = 0.065, n = 2 (since it's compounded semi-annually), and t = 5. Plugging in these numbers:
P = 200,000 / (1 + 0.065/2)^(2*5)
P = 200,000 / (1 + 0.0325)^(10)
P = 200,000 / (1.0325)^(10)
P = 200,000 / 1.37037037037
P = $145,946.33
