Question 1094299: Two factory plants are making TV panels. Yesterday, Plant A produced twice as many panels as plan B. Two percent of the panels from Plant A and 4% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 880 defective panels?

You can put this solution on YOUR website!
Let the number of panels produced by
plant B yesterday = +x+
+2x+ = number produced by plant A
yesterday
-----------------------
+.02%2A%28+2x+%29+%2B+.04x+=+880+
+.04x+%2B+.04x+=+880+
+.04x+=+440+
+x+=+11000+
---------------------------------
Plant B produced 11,000 panels
---------------------------------
check:
+.02%2A22000+%2B+.04%2A11000+=+880+
+440+%2B+440+=+880+
+880+=+880+
OK
