Answer:
Infinite solutions.
Step-by-step explanation:
Use the elimination method:
15x - 5y = -20
-3x + y = 4 Multiply this equation by 5:
-15x + 5y = 20 Now add this to the first equation:
0 = 0
So the 2 equations are the same and there are infinite solutions.
Building and solving an inequality, it is found that at a volume of sales of $11,875 he will start to earn more from the commission based compensation.
------------------------
- We want to find how much in dollars he has to sell such that 8% of this amount is greater than $950.
- Supposing he sells $x, 8% of this is represented by 0.08x. We want it to be greater than $950, thus, the inequality is:

Now we solve the inequality, similarly to how we would solve an equality.


At a volume of sales of $11,875 he will start to earn more from the commission based compensation.

coolio


so each term is ound by subtracting 13 from the previous term
an aritmetic sequence can be written as
were
is the nth term
is the first term
d is common difference, which can also be found by doing 
n=wich term
we know that
and we can find d
, 
so te general term is
which can also be expanded and written as
