Shonda purchases an annuity for 400000. The annuity will make payments at the end of each month for the next 30 years, using a nominal annual interest rate of 3.75% compounded monthly. Suppose that at the end of 15 years (immediately after receiving a payment), Shonda decides to sell the remaining annuity payments to George.

Give your answer rounded to the nearest whole number (i.e. X)
