Jim is his dad cook hamburgers for his family and friends. there are 15 people. each person wants two hamburgers. three people want hamburgers with cheese. two people want hamburgers with mustard. two people want hamburgers with catsup. the rest want them plain. how many plain hamburgers will jim and his dad make?

15 people, each want 2 hamburgers, so there will be 15*2 = 30 hamburgers.

However, we only want the plain hamburgers.

3 people want hamburgers with cheese: 30-3 = 27 plain hamburgers

2 people want hamburgers with mustard: 27-2 = 25 plain hamburgers

2 people want hamburgers with catsup: 25-2 = 23 plain hamburgers

Jim and his dad will make 23 plain hamburgers.

Hope this helps!! Let me know if you have ANY questions.

Yes of course i will indeed you with your problem.
