a compys quality control department found an average 5 defective models for every 1000 models that were checked. If the company produced 60,000 models in a year, how many if them would be expected to be in working order?

The best thing to do is to found out the percentage that is faulty. 1% is equal to 10 faulty products, therefore, 0.5% is equal to 5. In order to out how many there are in 60,000, you need to simply multiply 5 by 60, which is 300. Therefore, 300 are faulty. Hope this helps :)
