Question 1198081
**1. Determine the Number of Months**

* Life expectancy for a 50-year-old female in Japan: 87 years
* Years to live: 87 years - 50 years = 37 years
* Number of months to live: 37 years * 12 months/year = 444 months

**2. Calculate the Monthly Interest Rate**

* Annual interest rate: 6.8%
* Monthly interest rate: 6.8% / 12 = 0.5667%

**3. Calculate the Future Value of a Single Deposit**

* We need to find the future value of a single deposit that will grow to $10,000,000 in 444 months.
* Use the future value of an ordinary annuity formula:

   * FV = P * [(1 + r)^n - 1] / r 

   * Where:
      * FV = Future Value ($10,000,000)
      * P = Monthly Premium (unknown)
      * r = Monthly interest rate (0.005667)
      * n = Number of months (444)

**4. Solve for the Monthly Premium (P)**

* Rearrange the formula to solve for P:

   * P = FV * [r / ((1 + r)^n - 1)]

* Substitute the values:

   * P = $10,000,000 * [0.005667 / ((1 + 0.005667)^444 - 1)]

* Calculate P:

   * P ≈ $10,000,000 * [0.005667 / (15.236 - 1)] 
   * P ≈ $10,000,000 * [0.005667 / 14.236]
   * P ≈ $10,000,000 * 0.000398
   * P ≈ $3,980

**Therefore, the monthly premium for a 50-year-old female in Japan for a $10,000,000 life insurance policy would be approximately $3,980.**

**Note:**

* This calculation assumes that the interest rate remains constant over the entire 37-year period, which may not be the case in reality. 
* This calculation also assumes that the individual lives exactly to the life expectancy. 
* This is a simplified model and actual life insurance premiums are determined by various factors, including health, lifestyle, and other risk factors.
