Problema Solution
plant a produced 8000 fewer panels than plan b did. Two percent of the panels from plant a and three percent of the panels from plat b were defective. How many panels did plant a produce. If two plants together produced 640 defective panels.
Answer provided by our tutors
let 'x' represent the number of panels produced by plant b, then 'x-8000' represents the number of panels produced by plant a
640 = 0.03x + 0.02(x-8000)
solving for 'x' we have x=16000
16000-8000 = 8000
16,000 panels were produced by plant b
8,000 panels were produced by plant a
