From the information provided, A single-price monopolist earns a total profit of $80 when it produces and sells 20 units of its good. See the attached for more information.
<h3>How do we arrive at $80?</h3>
Total profit = revenue - cost
Revenue = price x number of units sold
Revenue at 20 units =
20 x9 = $180
Given that Total cost at 20 units is $100, thus,
Total Profit = 180 - 100

The other answers do not correctly use a semi-colon because the semicolon acts as a period that connects two closely related clauses.
The function shown in the graph in the image attached below is 
.
<u>Given the following data:</u>
- Points on the x-axis = (0, 4)
- Points on the y-axis = (0, 4)
First of all, we would determine the slope of this line by using the following formula;
Substituting the points into the formula, we have;
Slope, m = 1
Next, we would find the intercept:
Let x = 0, for the y-intercept.
b = 4
Therefore, the function shown in the graph in the image attached below is
