Edgar was entitled to a monthly life annuity of 400 at age 65, but died on the day before the first payment was due. A death benefit, equal in value to half the value of the annuity, was payable to his beneficiary. Edgar's beneficiary is his girlfriend Linda, aged 22.

The benefit is a 48-month temporary life annuity, commencing immediately, of X per month. Find X if D(,s = 100, Nes = 900, D22 = 2500, N22 = 53,000, D26 = 1950, and 7V26 = 43,500.
