A. 2 is the right answer
Step-by-step explanation:
Given function is:

The graph of any function is made by plugging in the inputs and finding the respective outputs hence creating points on graph.
The graph of function can be created using online graphing tools.
We have used the online graphing calculator "Desmos" to draw the graph of the given function (Picture Attached)
In the picture we can see that the line of graph intersects the x-axis on two points only.
Hence,
A. 2 is the right answer

Addition elimination.
This method is used to eliminate one of the two variables in the equations. This makes it easier to solve for the remaining variable.
All you have to do is find 40% or .4 of 90.
90 x .4 = 36
36$ is the mark up, so the total price would be 126$.
