Answer:
The Amount of money in the account after 20 years $22,416.
Step-by-step explanation:
Given as :
The principal deposited into account = $4000
The rate of interest = 9% compounded annually
The time period for deposit = t = 20 years
Let the amount into account after 20 years = $A
now, According to question
<u>From compound Interest method</u>
Amount = principal × 
Or, A = $4000 ×
Or, A = $4000 ×
Or, A = $4000 × 
or, A = $4000 × 5.604
So, The amount in account after t years = A = $22,416
Hence, The Amount of money in the account after 20 years $22,416. Answer
Step-by-step explanation:
5x+2y=29
5x-2y=41
add the equations
10x=70
divide both sides by ten
x=7
substitute 7 in the first equation
5(7)+2y=29
simplify
35+2y=29
subtract 35 from both sides
2y=-6
simplify
y=-3 x=7
3x+2y=9
5x+2y=12
subtract the equations
-2x=-3
simplify
x=1.5
substitute
3(1.5)+2y=9
simplify
4.5+2y=9
subtract 4.5 from both sides
2y=4.5
simplify
y=2.25 x=1.5
5x+2y=-9
2x-3y=4
multiply first equation by three and second by two
15x+6y=-27
4x-6y=8
add equations
19x=-19
simplify
x=-1
substitute
15(-1)+6y=-27
simplify
-15+6y=-27
add 15 to both sides
6y=-12
simplify
y=-2 x=-1
