Four years ago, Jacques purchased a perpetuity that agrees to pay him and his heirs $$150$ per month forever. At the time of purchase, Jacques was expecting to earn an annual return of $6\mathrm{.}00\%,$ but in the intervening years, the economy and the available investment alternatives have changed. In today$$s market, it is now reasonable to anticipate an annual return of $3\mathrm{.}60\%.$By how much would you expect the value of Jacques$$s perpetuity to change from when he purchased it until today?
