The amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
It is given that:
An investment account earns 4% per year compounded annually if the initial investment was $4000.
P = 4000
r = 4% = 0.04
t = 3
n = 1
Plug all the values in the formula, and we get:
A = 4000(1 + 0.04)³
A = $4499.45
Thus, the amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.

Answer:
1) one muffin costs $1.50
one quart of milk costs $3.00
2) 10 videos, 30 CDs
Step-by-step explanation:
1)
m = cost of one muffin
q = cost of one quart of milk
System of equations:
3m + 1q = 7.5
8m + 2q = 18
I multiplied the first equation by -2 to eliminate the 'q' values
-6m - 2q = -15
+ 8m + 2q = 18
2m = 3
m = 3/2
find 'q':
3(3/2) + q = 7.5
9/2 + q = 15/2
q = 6/2 or 3
2)
c = # of CDs sold
v = # of videos sold
System of equations:
c + v = 40
4c + 6v = 180
I solved first equation for 'c' to get c = 40 - v
4(40-v) + 6v = 180
160 - 4v + 6v = 180
2v = 20
v = 10
10 + c = 40
c = 30
