Answer:
Approx 37 years.
Step-by-step explanation:
The compound interest formula is :
Here, A = $50000
P = $5000
r = 6.5% or 0.065
n = 1
t = ?
Putting these values in formula we get;
=> 
=> 
Taking log on both sides;
=> 
We get t = 36.56 rounding to 37 years.
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12
