Question 1120829: Two factory plants are making TV panels. Yesterday, Plant A produced
6000
fewer panels than Plant B did. 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
1420
defective panels?

Since the problem asks for the number produced by plant B, it makes sense to make that our variable. So

let x = # produced by plant B
then x-6000 = # produced by plant A

5% of those produced by plant B and 3% of those produced by plant A were defective, for a total of 1420.

Write and solve the equation that says that:

.05%28x%29%2B.03%28x-6000%29+=+1420

You can do the simple algebra....
