Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.
*Answer*
y = -2
x = 5
*Step By Step Explanation*
To find y:
You’ll need to remove the x from the TOP equation, to do so,
You’ll need to find what is x + y, like so
2x + 2y = 6
x + y = 3
After you get this from division, subtract x + y from x + 3y and you’ll get this:
x + 3y - (x + y)
= x + 3y - x - y
= 2y
To find what 2y is, you have to subtract the value of x + y which is 3 from the value of x + 3y which is -1.
-1 - 3 = -4
Hence,
2y = -4
y = -2
To find x:
You would need to substitute the expression given with y. Like so:
x + 3y = -1
x + 3(-2) = -1
x - 6 = -1
x = 5
Hope it helps!
