Question

I legit do not know which it is.

Answer 1

Given:

The inequality is

$c\leq 7$

Where, c is the number of cars in the parking lot.

To find:

The graph for the given inequality.

Solution:

We have,

$c\leq 7$

Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.

Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.

In the graph of the given inequality, there are close circles on  0,1, 2,3,4, 5,6,7 as shown in option D.

Therefore, the correct option is D.
