Answer:
$346,581.52
Step-by-step explanation:
we need to use the present value formula to solve this:
present value = future value / (1 + r)ⁿ
the present value of tuition and books will be negative (since they are a cash outflow)
PV = -70,000 / (1 + 0.1) = -70,000 / 1.1 = -$63,636.36
PV = -140,000 / (1 + 0.1)² = -140,000 / 1.1² = -$115,702.48
the present value of the expected income will be positive since it represents cash inflows
PV = 700,000 / (1 + 0.1)³ = 700,000 / 1.1³ = $525,920.36
the net present value of obtaining a law degree = $525,920.36 - $63,636.36 - $115,702.48 = $346,581.52
