Answer:
Ian sold 7 rolls of wrapping paper.
Step-by-step explanation:
Let E be the number of rolls of wrapping paper sold by Evan and I be the number of rolls of wrapping papers sold by Ian.
We have been given that Evan sold twice as many rolls of wrapping paper as Ian. We can represent this information in an equation as:
We are also told that Evan sold 14 rolls.
We can represent this information in an equation as:
To find the number of rolls of wrapping paper sold by Ian we will equate our both equation as:
Let us divide both sides of our equation by 2.
Therefore, Ian sold 7 rolls of wrapping paper.

Answer:
a. Chart (attached)
b. and c. graph attached
Step-by-step explanation:
a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.
So, when x=0, 
when x=20, 
when x=40, 
b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)
c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
