Answer:
The continuous yearly interest is 22.5% per year.
Step-by-step explanation:
Continuous yearly interest:
Continuous yearly interest is defined as the sum of the interest comes from principle and the interest comes from interest.
The formula for continuous interest yearly is

where A = The final amount =$110,000
P= principle =$4,700
r= rate of interest
t= time (in year)= 14 years


Taking ln both sides



(approx)
The continuous yearly interest is 0.225 = 22.5% per year.
1-When you have a the logarithm given in the problem above, you can solve it by using the correct properties for logaritms.
2- The students could solve it as below:
<span>log4(2x-12)=3
4^[</span> log4(2x-12)]=4^3
3- By definition a^log(x)=x, therefore,
2x-12=4^3
2x-12=64
4- Now, the students can solve for x:
x=38
The first step is incorrect, because the term on the right member must be 4^3.
