2 factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Two percent of the panels from Plant A and 5% of the panels from Plant B we’re defective. How many panels did Plant B produce, if the two plants together produced 1140 defective panels

Respuesta :

Answer:

Number panels Plant B produce = 18,000

Step-by-step explanation:

Given:

Plant produces defective panels = 1140

Plant B produce = 5%

Plant A produce = 2%

Find:

Number panels Plant B produce

Computation:

Assume

Number panels Plant B produce = x

Number panels Plant A produce = x - 6000

So

5%(x) + 2%(x-6000) = 1140

0.05x + 0.02x - 120 = 1140

0.07x = 1260

x = 18,000

Number panels Plant B produce = 18,000
