Answer:
1. 2,584
Explanation:
future payments: $1,000 in 1 year and $2,000 in 3 years
the present value of alternative I (one year bond):
$1,000 / 1.06 = $943.40
the present value of alternative II (first 2 years and then 1 year):
$2,000 / 1.065 = $1,877.93 ⇒ PV at year 2
PV at year 0 = $1,877.93 / 1.07² = $1,640.26
the total present value of both options = $943.40 + $1,640.26 = $2,583.66 ≈ $2,584
