Two factory plants are making TV panels.

Question

Two factory plants are making TV panels. Yesterday, Plant A produced 4

 times as many panels as Plant B. Three percent of the panels from Plant A and 5%

 of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 2040

 defective panels? 



Answer 1

A=4B

.03A + .05B = 2040

solve by substitution elimination or matrix algebra

B = 12,000 panels

A = 48,000 panels
