For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
<h2>
Hello!</h2>
The answer is $101688
<h2>
Why?</h2>
Since there is not enough information about the rate, let's assume that it's a daily rate.
<h2>Calculations</h2>
Let's say:
P : Proceeds
o : original amount
d : number of days
r : percentual rate
So,

Let's make the percentual rate (6,5%) a real number by dividing into 100,

By substituting, we have

$101688
Have a nice day!
