I don't understand please help ​
dybincka [34]

Answer:

Step-by-step explanation:

If she sells 8 dozen, she will get exactly 120 dollars. But that is not what the question says.

Sales = 8 * 15 = 120

The question says that she wants to make more than 120 dollars. Therefore the circle must be an open one. B is the proper answer. A is close but A means that she is willing to stop her sales when they reach 120 dollars. Not so.

A is not the answer.
