im pretty sure the answer is 30
Answer:
the constant propertianr would be 4!
Step-by-step explanation:
1 times 4 is 4
2 times 4 is 8
3 times 4 is 12
4 times 4 is 16
I'll use my own formula (similar to yours tho)

A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years
so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so

divide both sides by P

simplify


take the ln of both sides



divide both sides by 4ln(1.03)

use calculator
5.86244=t
about 5.9 years
Here is your answer:
Your answer is 18%
Reason: That's because 18 has a invisible decimal point:
18.
Then you move to decimal and change it into a %
Which will make it 18%
Your answer is...
