Answer: 3%
Step-by-step explanation:
S.I = ptr / 100
Interest = 4515 - 4500
Interest = 15
time = 4 months = 4/12 years = 1/3 years
substituting each value into the equation to find rate , we have
15 = 4500 x 1/3 x r / 100
1500 = 4500 x 1/3 x r
3(4500) = 4500r
r = 3(4500) / 4500
r = 3%
The formula to use is
A=p(1+(r/n))^(nt)
P= principle
R= rate
N= number of times it's compounded per year
T= time in years
Quadruple means 4 times
24000=6000(1+.035)^t
Divide by 6000
4= (1.035)^t
To bring the variable out of the power you take the log of both sides.
Log4= t Log1.035
Divide both sides by log1.035
(Log4)/(log1.035)=t
40.30=t
