Hello, there!
5/4 = 1.25
So, we know that the answer is not A or B.
1.25 = 125%
Now, we know that the answer is not D ether.
So, the answer must be C.
I hope I helped!
Let me know if you need anything else!

Part A would be 2 lines below the surface because since he is 2 lines above the surface (represented by +10 feet).
Part B would be -50 feet because he would be BELOW the surface (represented by "-", like -45).
Part C would be 20 because DeWayne would be at the tip of the seaweeds, -20 feet. Since each line is 5 feet, then he would have to swim 20 feet up to reach the surface.
Part D would be 0 feet. Since one line above the surface is 5, and one line below the surface is -5, subtracting or adding 5 would be 0.
:)
Hope this helped,

Answer:
![y = 7e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%207e%5E%7B-3t%7D)
Step-by-step explanation:
![y = C_1e^{3t} + C_2e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%20C_1e%5E%7B3t%7D%20%2B%20C_2e%5E%7B-3t%7D)
implies that when
,
.
![7 = C_1e^{3\times0) + C_2e^{-3\times0}](https://tex.z-dn.net/?f=7%20%3D%20C_1e%5E%7B3%5Ctimes0%29%20%2B%20C_2e%5E%7B-3%5Ctimes0%7D)
![7 = C_1+C_2](https://tex.z-dn.net/?f=7%20%3D%20C_1%2BC_2)
For the condition
, as
,
.
In the expression for
, as
, the term containing
vanishes. Hence,
![0 = C_1e^{3t}](https://tex.z-dn.net/?f=0%20%3D%20C_1e%5E%7B3t%7D)
![C_1 = 0](https://tex.z-dn.net/?f=C_1%20%3D%200)
Since ![7 = C_1+C_2](https://tex.z-dn.net/?f=7%20%3D%20C_1%2BC_2)
![7 = 0+C_2](https://tex.z-dn.net/?f=7%20%3D%200%2BC_2)
![C_2 = 7](https://tex.z-dn.net/?f=C_2%20%3D%207)
Substituting for
and
in
,
![y = 7e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%207e%5E%7B-3t%7D)
Answer:
1st week deposit= 2b+3
2nd week deposit=2(2b+3)
3rd week deposit=4(2b+3)
Total deposit=2b+3+2(2b+3)+6(2b+3)
=9(2b+3)
=18b+27
18b+27=477
18b. =477-27=450
18b. =450
;
b=450/18=25
Therefore 2b+3=2(25)+3 =50+3=53
