Answer: I got 23/10, or 2.3
Step-by-step explanation:
14/11 or 1 3/11
hope this helps.
A=future amount
P=present amount
r=rate in decimal
t=time in years
when A=2P, then that is double
A=Pe^(rt)
2P=Pe^(rt)
divide by P
2=e^(rt)
r=3.1% or 0.031 solve for t
2=e^(0.031t)
take the ln of both sides
ln(2)=0.031t
divide both sides by 0.031
(ln(2))/0.031=t
use calculator
22.359=t
round to tenth
22.4 years to double
The answer might be 4,245because 14x3=42 & 5x9=45 there is ur answer
