Mel's movie house prepares for 30% more people than expected attendence at the movie each day. How many people should mel prepare popcorn for the plan for 850 movies goers?

my answer is 225 but I thing its wrong can someone help me ASAP

hard to say what went wrong, since you declined to show your work.

First, your question makes no sense. If he plans for 850 moviegoers, then he needs to prepare 850 popcorns, right?

If the normal crowd is 850, then he needs to plan for 850 * 1.30 = 1105
If he needs to plan for 850, then the normal crowd is 850/1.30 = 653.8
