Answer:
C
Step-by-step explanation:
We are trying to find the profit for every pizza sold. Since looking at the x axis, the point in which its x coordinate is 1 cannot be easily identified. Thus, we shall derive the answer using a point that can be easily identified.
We observe that the two points, (10,12) and (20,24) sits nicely on the graph. I will be using the first coordinate above to derive the answer.
For every 10 pizzas sold, $12 of profit is made.
10 pizzas ----- $12 profit
1 pizza ----- $12 ÷10= $1.20
Hence, the unit rate of profit for the pizzas is $1.20 per pizza.

Step-by-step explanation:
The question is incomplete, as the required number line is not included in the question.
A general explanation is as follows:
An open circle means > or <
A closed circle means >= or <=
Take, for instance, the attached number line:
The open dot on -3 means >-3 or <-3
The arrow points to the right direction, means >-3 i.e. greater than -3
Hence, the inequality is:
First guess: 1200
Second guess: 106
Nope.
Natural numbers consist of 1, 2, 3, 4 and so on. Integers, on the other hand, include 0 and the opposites of natural numbers (negative values). Therefore not all integers are natural numbers. Some of them are though.
