Two factory plants are making tv panels. yesterday, plant a produced 6000 panels. seven 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 4 % ?

1% of 4000 + 4% of B = 2% of (4000 + B)

40 + 0.04*B = 0.02( 4000 + B)

40 + 0.04* B = 80 + 0.02*B

40 + 0.04*B - 80 - 0.02B = 0

0.02*B - 40 = 0

0.02*B = 40

2B = 4000

B = 2000
