Answer:
Accumulated amount will be $2504.90.
Step-by-step explanation:
Formula that represents the accumulated amount after t years is
A = 
Where A = Accumulated amount
= Initial amount
r = rate of interest
n = number of times initial amount compounded in a year
t = duration of investment in years
Now the values given in this question are
= $1000
n = 12
r = 4.6% = 0.046
t = 20 years
By putting values in the formula
A = 
= 
= 
= 1000×2.50488
= 2504.88 ≈ $2504.90
Therefore, accumulated amount will be $2504.90.
Ok so let us label our equations first
1- 3x+2y+z=7
2- 5x+5y+4z=3
3- 3x+2y+3z=1
subtracting equation 3 from equation 1
3x+2y+3z=1
(-). 3x+2y+z= 7
----------------------
2z=-6----->z=-3
since we already chose equation 1 and 3 we must involve equation 2
substituting the value if z in the second equation
5x+5y-12=3
5x+5y=15
choosing either the first or the third
3x+2y-3=7
3x+2y=10
solving the system
5x+5y=15
3x+2y=10
multipling the first equation by 2 and the second equation by 5
10x+10y=30
15x+10y=50
subtracting the two equations
-5x=-20--->x=4 substituting for the value of x
40+10y=30--->10y=-10y--->y=-1
so our soultion is x=4,y=-1,z==-3 or (4,-1,-3)
The answer for the quest is x=2
