Question

Two factory plants are making TV panels. Yesterday, Plant A produced 7000 fewer panels than Plant B did. Four 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 two plants together produced 620 defective panels?

Answer 1

Step-by-step explanation:

17000

Let the number of panels Plant B produced be x.

$7000(0.04)+0.02x=620 \\ \\ 0.02x=340 \\ \\ x=17000$
