Two factory plants are making TV panels. Yesterday, Plant A produced 4000 panels. Six 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 overall percentage of defective panels from the two plants was3%?

12,000 panels are produced by Plant B.

Step-by-step explanation:

The percentage of defective panels,

6% of plant A + 2% of plant B = 3% of both A and B

6/100(4000) + 2/100(x) = 3/100(4000+x)

240 + 0.02x = 120 + 0.03x

240-120 = 0.03x-0.02x

120 = 0.01x

x = 120/0.01

x = 12,000

The plant B produced 12,000 panels.

where are the options?

step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
