Well actually number nine shows a fraction. There is no percent shown.
Answer: Work done by both of them in k hours is
![\frac{k(x+y)}{xy}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%28x%2By%29%7D%7Bxy%7D)
Explanation:
Since we have given that
Number of hours Mr. I does a job = x hours
Number of hours Mr. L does a job = y hours
Work done by Mr. I is given by
![\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D)
Work done by Mr. L is given by
![\frac{1}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%7D)
Work done if they do together is given by
![\frac{1}{x}+\frac{1}{y}\\\\=\frac{x+y}{xy}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%2B%5Cfrac%7B1%7D%7By%7D%5C%5C%5C%5C%3D%5Cfrac%7Bx%2By%7D%7Bxy%7D)
Work done if they work together for k hours is given by
![\frac{x+y}{xy}\times k\\\\=\frac{k(x+y)}{xy}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2By%7D%7Bxy%7D%5Ctimes%20k%5C%5C%5C%5C%3D%5Cfrac%7Bk%28x%2By%29%7D%7Bxy%7D)
Hence, work done by both of them in k hours is
![\frac{k(x+y)}{xy}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%28x%2By%29%7D%7Bxy%7D)

Hope this helps!
Step-by-step explanation:
We will need the loan payment formula:
That formula is really complex and we expect you to solve it.
Your monthly payment would be $1.93 per month for 6 years making the TOTAL loan cost 1.93 * 12 * 6 = 138.96
Since the principal you borrowed is $120 the total interest =
(138.96 minus 120.00) which equals $18.96
Ratio of volume is a cubed: b cubed
