Problema Solution

Two factory plants are making tv panels. yesterday plant a produced 8000 fewer panels than plant B did. Three percent from plant A, and 5% of the panels from plant B were defective, how many panels did plant A produce, if the two plants together produced 1600 defective panels

Answer provided by our tutors

let 'x' represent the number of panels produced at plant A, then 'x+8000' represents the number of panels produced at plant B


1600 = 0.03x + 0.05(x+8000)

solving for 'x' we have x=15000


15000+8000 = 23000


plant A produced 15,000 panels
