Step-by-step explanation:
the equation will be
-4(7+n)=3n
let's solve the equation
-28-4n=3n
add 4n to the both sides
the equation becomes
-28-4n+4n=3n+4n
-28=7n
divide both sides by 7
-4=n
or
n=-4

Answer:
4.38%
Step-by-step explanation:
<em>Assuming simple interest</em>, we start by writing the formula for simple interest.

Where
SI is the interest amount (328.13)
P is the principal amount (2500)
r is the rate of interest (what we need to find)
t is the time, in years (t = 3)
Since we want rate of interest, we re-arrange the formula to get r in terms of the other variables. Shown below:

Now we simply plug-in the information we know and find r:

To convert into percentage, we multiply by 100:
r = 0.0438 * 100 = 4.38%
