Answer:
great!
Step-by-step explanation:
how about you?
Given:
Mr. Sun borrowed $15,600 for 54 months at simple interest.
Mr. Sun paid the bank a total of $21,567.00.
To find:
The rate of simple interest.
Solution:
We know that,
12 months = 1 year
1 month =
year
54 months =
year
54 months = 4.5 years
Simple interest is:
![S.I.=Amount-Principal](https://tex.z-dn.net/?f=S.I.%3DAmount-Principal)
![S.I.=21567-15600](https://tex.z-dn.net/?f=S.I.%3D21567-15600)
![S.I.=5967](https://tex.z-dn.net/?f=S.I.%3D5967)
Formula for simple interest is:
![S.I.=\dfrac{P\times r\times t}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7BP%5Ctimes%20r%5Ctimes%20t%7D%7B100%7D)
Where, P is principal, r is the rate of interest in percent and t is the number of years.
Putting
, we get
![5967=\dfrac{15600\times r\times 4.5}{100}](https://tex.z-dn.net/?f=5967%3D%5Cdfrac%7B15600%5Ctimes%20r%5Ctimes%204.5%7D%7B100%7D)
![596700=70200r](https://tex.z-dn.net/?f=596700%3D70200r)
![\dfrac{596700}{70200}=r](https://tex.z-dn.net/?f=%5Cdfrac%7B596700%7D%7B70200%7D%3Dr)
![8.5=r](https://tex.z-dn.net/?f=8.5%3Dr)
Therefore, the rate of simple interest is 8.5%.
24,805 I think that's the u mean but I'm not sure
Im going to guess B., obtuse. i know botuse angles go from 100-160 degrees. sorry if im wrong, but im sure im not.
Work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
