Answer:

Step-by-step explanation:
From the graph, 
The initial red incline is a straight line passing through the origin.
So, a straight line passing through the origin is of the form:

Where, 'm' is the slope.
Now, the slope of a given as the change in y value to change in x value.
Consider the two end points of the red line (0, 0) and (4, 6).
The slope with two points  on the line is given as:
 on the line is given as:

Plug in  . Therefore, slope is:
. Therefore, slope is:

Hence, the equation of the initial red incline is:

 
        
             
        
        
        
Answer:
960
Step-by-step explanation:
Over here, I'm going to do it in two ways, and either way works, one is just easier to do out:
1st way:
You can represent the percent 120 as a decimal which is 1.20, then you do 800*1.2.
2nd way:
You can use benchmark percents. You find 10 percent of 800 which is 80 and multiply 80 by 2 to get 160, so 20% is 160 dollars. Then you add 160 to 800 (800+160) and get 960.
Please tell me if you have any questions.
