Problema Solution
Two factory plants are making TV panels. Yesterday, Plant A produced 2000 panels. Two percent of the panels from Plant A and 5 percent of the panels from Plant B were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 4 percent ?

To find the total number of panels, 'x':
.02(2000)+.05(x-2000)=.04x
x=6000
Number of panels from plant B:
x-2000=6000-2000= 4000 panels
