Question 1048242: To factory plants are making TV panels. Yesterday, Plant A produce twice as many panels as plant B. 5% of the panels from plant A and 3% of the panels from plant B were defective. How many panels did plant B produce if the two two panels together produced 910 defective panels
Answer by jorel555(1290) (Show Source): You can put this solution on YOUR website!
Let n be the amount of panels produced by plant B. Then plant A is 2n. So:
.05(2n)+.03(n)=910
.13n=910
n=7000 panels produced by plant B; 14000 panels produced by plant A. ☺☺☺☺
