The Manufaturing Company allows the defect rate of 0.5% on its production line. The defect average for last week was 6 items out of 1,800. What is the difference between the allowed defect rate and the defect average for last week?

.5percent is 1 per 200. How many 200's are there in 1800?

sorry never mind I don't need it
