8p + 3a = 213 and p + a = 41 are the two required equations which will give us the number of phones and accessories sold by Levi.
<u>Solution:</u>
Levi earns a $8 commission for every phone he sells and a $3 commission for every accessory he sells.
On a given day, Levi made a total of $213 in commission from selling a total of 41 phones and accessories.
We have been asked to write a system of equations that could be used to determine the number of phones sold and the number of accessories sold. We also have to define the variables that you use to write the system.
Let us denote the number of phones as ‘p’ and number of accessories as ‘a’
So, we can write the following equations from the given data:
Given that levi made $ 213 commission
8p + 3a = 213
And, Levi sold 41 phones and accessories. So we can frame a equation as follows:
p + a = 41
These two equations can be used and solved to determine the number of phones and accessories sold.
The dot means to multiply
so 43 x 10025 -50
since BEDMAS is applied,
we would do the multiplication first
43 x 10025 = 431075
and <span>431075 - 50 is 431025
FINAL ANSWER: 431025</span>

Answer:
see attached
Step-by-step explanation:
a) A system of equations has no solutions when the graphs of those equations do not intersect. If the equations are equations of a line, then the lines must be parallel in order for them not to intersect.
Any parallel line will do.
__
b) There is one solution when the graphs intersect in exactly one point.
Any line that crosses the one shown will do.
__
c) There are infinite solutions when the graphs describe the same curve.
A line overlapping the one shown is the one you want.
