If you then want to go on to factor it, your answer would be
Answer:
Rate=9.05%
Step-by-step explanation:
Let P represent the Principal ,t the time = 8 years and r be the rate of interest.
It is given money doubles in 8 years so A=2P.
The compound interest is given by the formula :

Substituting the values we have:

Dividing both sides by P :


1.0905-1=r
r=0.09050
r=9.05%
Answer:
it can't pe proven ..... is the right answer of this question...
