A group of 120 people were asked whether their income level is above or below $25,000 and whether they subscribe to a movie chan
nel. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table.
Which shows the correct values for the variables in the table?
A: a = 18, b = 34, c = 65
B: a = 34, b = 18, c = 68
C: a = 34, b = 68, c = 47
D: a = 47, b = 18, c = 68

Start by graphing each line.
• Because the first inequality is smaller than, it will have a dotted (- - -) line.
• Because the second inequality is smaller than or equal to, it will have a solid line (---).
Then, plug in points to see where your shading will go. If the statement is true (x = x), you will shade that area along the line.
0 is less than 2.
Do the same step for the other equation. Your solution to the problem is any point that lies between the shading from both inequalities (where the blue and red meet).
