Answer: 64 years
Step-by-step explanation:
Let assume the dealer sold the bottle now for $P, then invested that money at 5% interest. The return would be:
R1 = P(1.05)^t,
This means that after t years, the dealer would have the total amount of:
$P×1.05^t.
If the dealer prefer to wait for t years from now to sell the bottle of wine, then he will get the return of:
R2 = $P(1 + 20).
The value of t which will make both returns equal, will be;
R1 = R2.
P×1.05^t = P(1+20)
P will cancel out
1.05^t = 21
Log both sides
Log1.05^t = Log21
tLog1.05 = Log21
t = Log21/Log1.05
t = 64 years
The best time to sell the wine is therefore 64years from now.
1) A=100(1+0.05/12)^12t
2) 125=100(1+0.05/12)^12t
125/100=(1+0.05/12)^12t
Log(125/100)=12t*log(1+0.05/12)
12t=log(125÷100)÷log(1+0.05÷12)
t=[log(125÷100)÷log(1+0.05÷12)]/12
T=4.5 years
