first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3

Answer:
The amount of interest earned for the year is $37.7
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents principal or amount invested.
T represents the time
R represents the interest rate
I represents the interest
From the information given,
You want to put $580 into a saving account for 1 year. This means that
P = $580 and
T = 1 year
R = 6 1/2 = 6.5%
I = (580× 6.5×1)/100 = $37.7
