<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
David keeps a range of stationery in his study.
Let the pencil is represented by x.
Let the erasers be represented by y.
Let the pens be represented by z.
Let n be the stationery.
5/7 of his stationery consists of pencils.
x = 5/7 n
1/6 of the remaining stationery consists of erasers.
y = 1/6 n
There are 20 pens in his study.
z = 20
The total stationery
X + y + z
5/7 n + 1/6 n + 20 = n
20 = n -23/ 36 n
20 = 13 / 36 n
n = 55.38
Therefore, the total units of stationery he has would be 55 approximately.

Answer:
$48,672
Step-by-step explanation:
% of commission earned by Nadia = 13% of sale stock
Value of sale stock = $7,200
weekly commission earned by Nadia in $ = 13% of $7,200 = $936
It is given that she averages that same amount each week means that
her weekly earning for each week remains same i.e $936
There are 52 weeks in a year
so total earning by Nadia in a year = $936*52 = $48,672
As question asks how much did she make in commission in 2011.
It means her yearly income in 2011 is being asked which as calculated above is $48,672.
