STEP-BY-STEP EXPLANATION:
What to find? Number of panels plant B produced
Given parameters
The total number of defective panels produced by two plants = 480
The percentage of defective panels produced by plant A = 2%
The percentage of defective panels produce
Let the number of panels produced by A be x
Let the number of panels produced by B be y
According to the question, Plant A produced twice as many panels as plant B
This implies that for every 1 panel produced by A, Plant B will produce 2
The above can be expressed mathematically as
[tex]x\text{ = 2y ------------ equation 1}[/tex]
