Answer:
c)Mary is glad she borrowed the funds because her real interest rate has fallen.
Explanation:
Real interest rate = nominal interest rate - inflation rate
=8% - 6% = 2%
Mary is willing to pay a real interest rate of 3% but she pays 2%. Her consumer surplus is 1%
Joe is willing to accept 3% but receives 2% in the end. Therefore, he doesn't earn a producer surplus.
