Answer:

B produced 20000 panels

Step-by-step explanation:

Plant A produced 5000 fewer panels than Plant B did

A = B - 5000 eq1

Two percent of the panels from Plant A and 4% of the panels from Plant B were defective:

0.02A + 0.04B = 1100 eq2

Solving the two equations:

Put value of A from 1 in 2

0.02 (B - 5000) + 0.04B = 1100

0.06B - 100=1100

0.06B = 1200

B = 20000
