D = c-s/n
Dn = n(c-s/n)
Dn = c - s
Dn + s = c
<u><em>c = Dn +s</em></u>
Answer:
The final balance is $853.63.
The total compound interest is $453.63.
The compound interest on initial balance is $59.47.
The compound interest on additional deposits is $394.16.
The final balance of initial money is $459.47.
The final balance of additional deposit is $394.16.
The sum of the additional deposits is $0.
The total principal (initial balance plus total additional deposits) is $400.

Hello from MrBillDoesMath!
Answer:
x = 3
Discussion:
(
23 + 3x) + (8x-41) = 15 =>
23 - 41 + 3x + 8x = 15 =>
-18 + 11x = 15 =>
11x = 15 + 18 = 33 =>
x = 33/11 = 3
Thank you,
MrB
Generic exponential growth model: y = Ao[1+r]^t
In this case: r = 3.5% = 0.035
y = 2Ao .....[the double of the initial value]
Then: 2Ao =Ao (1 + 0.035)^t
(1.035)^t =2
Take logarithm to both sides
t ln(1.035) = ln(2)
t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15
Answer: 20.15 hours.
Assuming that angles X and Z are the same as A and C, the Y angle must be 75 degrees. It's because the sum of all three angles in any triangle give us 180 degrees, so:
180 - 45 - 60 = 75 degrees
