Step-by-step explanation:
1. To solve this exercise you must observe the graph attached in the problem, where the intensity of the sound is represented in the x-axis and the decibel measure is represented in the y-axis.
2. As you can see in the graph, when the value of x is 500 (x=500) the value of y is 28 (y=28).
