Answer: a. $417.2. b. $383.51. c. $400 today.
Step-by-step explanation:
a. Present value = $400
Interest rate = 4.3%
Future value= PV(1+r)^n
= 400(1+0.043)^1
= 400(1.043)
= $417.2
b. FV = $400
PV = Unknown
Interest = 4.3%
Future value= PV(1+r)^n
400 = PV(1+0.043)^1
400 = PV(1.043)
PV = 400/1.043
PV = $383.51
c. I'll prefer $400 today.
My answer does not depend on me needing money presently, I can actually invest the $400 today and get more value when it's a year. I'll have made more than $400.
