Answer: 175
Step-by-step explanation: First, a group of five hundred combs produces 34 defective combs. So if they make 2,500, you multiply how many times you add 500 to get to 2,500, which should be 5. Now multiply that to 34 and you get 175! To check it, divide: 34 divide by 150. Hope this helps!
