Answer:
88%
Step-by-step explanation:
The correct answer is 88% because 12% of the pens are defective.
As a result, 12% ÷ 5000 = 12 ÷ 100 x 5000
= 600
There are 600 defective pens.
The pens that are left are 5000 - 600 = 4400.
4400 pens are in good working order.
This means that 88 percent = 4400 ÷ 5000 x 100
I hope this helps! ^-^
