Answer:
15 years.
Step-by-step explanation:
We have the equation:
20000 = 10000(1 + 0.048)^t where t is the number of years.
1.048 t = 20000/10000 = 2
Taking logs:
t ln 1.048 = ln 2
t = ln 2 / ln 1.048
t = 14.78
First option
√31 = 5.56....
√26 = 5.09....
So m is less than k but greater than 5.
k is greater than k but less than 6.
So the first option is more logical
-9,4
