Find the price before the 15% profit:
2500 / 1.15 = 2173.91
Now multiply the original cost by 1 + 38%:
2173.91 x 1.38 = 2999.99
Answer: 2.999.99 ( may need to round to 3,000)
6 is the value of x in this
Average of 5 games = 13
Total of 5 games = 13 x 5 = 65
Average of 6 games = 17
Total of 6 games = 102
6th game = 102 - 65 = 37
---------------------------------------------------------------------
Answer: Her score for the 6th game as 37.

Answer:
b = 310
Step-by-step explanation:
192 + 118 = b
b = 310
or 
is very easy to graph.
Choose whatever value of 
and use the same for 
in the same coordinate. Repeat and strike a line through all the points.
Some examples of valid points would be: 
, 
, 
and 
.
Then, to graph 
you have to look at it in terms of the equation of a line (
) and its parts.
In this case, 
and 
.
So, you choose any value for and you solve to find its counterpart.
I will start with 
:
Now, we have a first coordinate: 
.
Repeat with a different value:
It gives us the coordinates 
.
Plot those into the graph and strike a line through them.
Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be 
.
You can check it by replacing and by "3" in both formulas and equating the values of :
Your solution is worked out and checked to be correct.
PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
