<u>Part C:</u>
The company breaks even when the profit is positive. From the graph of the function you can see that the graph of the function is over p-axis for all
, so the positive profit is for 
In p=16 and p=20, the profit is 0 and when p<16 and p>20, there will be a loss.
-16 - 8/2 + 25 / 5 +1
-16 -4 + 5 +1
-20 +6
-14
