Total number of weeks in 25 years = 52 * 25 = 1,300
Interest rate per week = 6% / 52 = 0.1154%
The Present Worth of receiving $1,000 per week = A(P/A, 0.1154%, 1300)
= 1,000(673.069)
= $673,069
Since the present value of weekly payment is less than the one time payment of $675,000, therefore, one time payment option is better.
