Two factory plants are making tv panels. yesterday, plant a produced 4000 panels. one 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 overall percentage of defective panels from the two plants was 3%?

8000

Step-by-step explanation:

---

0.1x + 0.03y = 0.06(x + y)

0.1*6000 + 0.03y = 0.06(6000 + y)

600 + 0.03y = 0.06*6000 + 0.06y

0.06y - 0.03y = 600 - 360

0.03y = 600 - 360

y = (600 - 360)/0.03

y = 8000

---

y = panels produced by plant B = 8000

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
