Answer:
As x increases, y decreases and then increases
Step-by-step explanation:
You need only understand your own description of the graph:
begins above the x-axis, extends below the x-axis, and ascends above the x-axis
This is a description of <em>decreasing</em>, then <em>increasing</em>:
As x increases, y decreases and then increases
First, turn 30% into a decimal
30% / 100 = 0.3
Second, multiply.
0.3 * 67 = $20.10 is the discount
Third, subtract.
67 - 20.1 = $46.90 is the total price of the dress.
Best of Luck!
