Question 1098426
Two factory plants are making TV panels. Yesterday, Plant A produced 
24,000
 panels. Six percent of the panels from Plant A and 
2%
 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 
5%
<pre>Defective panels from Plant A: .06(24,000) = 1,440
With 2% of Plant B's and 1,440 of Plant A's panels being defective, and 5% of the total panels (Plant A + Plant B) being defective, we get: .02B + 1,440 = .05(B + 24,000)	
.02B + 1,440 = .05B + 1,200	
.02B - .05B = 1,200 - 1,440	
 - .03B = - 240	
Number of panels produced by Plant B, or {{{highlight_green(matrix(1,5, B, "=", (- 240)/(- .03), "=", "8,000"))}}}
