Answer:
1387.5 meters
Step-by-step explanation:
Sea level is 0
it descends 92.5 m every minute
so the equation will be d=0-92.5m where d is distance and m is minutes
so you want to find out how far it will be after 15 minutes - substitute
d=0-92.5(15)
simplify
d=0-1387.5
solve for d
d=-1387.5
the submarine will 1387.5 meters from its starting position

Given that the cost price (C) is $399 and the selling price (S) of the television is $662.34,
It is asked to find that by how much percentage is the television price marked up.
This can be calculated as follows,
![\begin{gathered} \text{Mark up}=\frac{S-C}{C}\times100 \\ \text{Mark up}=\frac{662.34-399}{399}\times100 \\ \text{Mark up}=\frac{263.34}{399}\times100 \\ \text{Mark up}=0.66\times100 \\ \text{Mark up}=66 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BMark%20up%7D%3D%5Cfrac%7BS-C%7D%7BC%7D%5Ctimes100%20%5C%5C%20%5Ctext%7BMark%20up%7D%3D%5Cfrac%7B662.34-399%7D%7B399%7D%5Ctimes100%20%5C%5C%20%5Ctext%7BMark%20up%7D%3D%5Cfrac%7B263.34%7D%7B399%7D%5Ctimes100%20%5C%5C%20%5Ctext%7BMark%20up%7D%3D0.66%5Ctimes100%20%5C%5C%20%5Ctext%7BMark%20up%7D%3D66%20%5Cend%7Bgathered%7D)
Thus, the mark up is 66%.
