Question

Two factory plants are making TV panels. Yesterday, Plant A produced 4 times as many panels as Plant B. Three 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 1260 defective panels?

Answer 1

Explanation:

x=# of panels plant B produced

3x=# of panels plant A produced

2%(x)+5%(3x)=1360

0.02(x)+0.05(3x)=1360

0.02x+0.15x=1360

0.17x=1360

17x=136,000

x=136,000/17

x=8,000 panels were produced by plant B
