The answer to your question is: letter D
Step-by-step explanation:
The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:
5 < x ≤ 9
a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.
b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].
c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.

Answer:
Allen sold 50 cell phones while Kay sold 67 cell phones.
Step-by-step explanation:
Let the number of cell phones sold by Allen be x. This will imply that the number of cell phones sold by Kay is x + 17.
Furthermore, we are informed that together they sold a total of 117 cell phones. Therefore, we use the following equation to determine the number of cell phones sold by each;
x + x + 17 = 117
2x + 17 = 117
2x = 100
x = 50
Therefore, Allen sold 50 cell phones while Kay sold 67 cell phones.
