How much more money does he gain in

making this choice?

1 answer

value of 125000 6 months from now
= 125000(1.00416666...)^6
= 128157.73

Pr value of 135000
x(1.00416666..)^6 = 135000
x = 131673.68

So both solutions show that he should take the 135000 six months from now.

At he present time, the difference is worth
= 131673.68 - 125000
$ 6673.68

Six months from now the difference is worth
135000 - 128157.73 =6842.27

notice that
6673.68(1.00416666..)^6 = 6842.27
