She found that of 1,000 orders, 550 customers ordered turkey, 305 ordered ham, and 225 customers ordered neither turkey nor ham. Based on this data, how many of the next 1,000 customers will order both turkey and ham?

80?

What I did was add all of them together and get the sum of 1080, which is 80 people too much. This explanation I found is better. https://answers.yahoo.com/question/index?qid=20140402153200AAKJozE

That's what I thought originally but I know that isn't the answer. Usually I find the answers to these type of problems by just multiplying the turkey and ham percentages to get a new percent. The problem is that, despite getting the right answer, that isn't the way the book taught it so I can't put it as my explanation

Not even the link helped? It also got the answer 80 using a method completely different from mine.

Really? I'll give it a shot. I'm sure that as long as I show some kind of thought process I'll get more credit than just a guess with no explanation. Thank you!
