Answer:
$31,046
Explanation:
real interest rate = nominal interest rate - inflation
4% = nominal interest rate - 6% ⇒ nominal interest rate = 10%
if you want to determine the present value of the fifth payment, and you require a 4% real interest rate, the you must use a discount value = nominal interest rate
present value = payment / (1 + rate)⁵ = $50,000 / (1 + 10%)⁵ = $50,000 / 1.1⁵ = $50,000 / 1.61051 = $31,046
