Linear Programming help
OK, so I'm 19 and I'm a server at a new, local bistro. Lately the business has been getting very few customers. (It only opened three months ago, not a good time since most people are getting their kids back to school around this time, but even still I live in a small town where most people aren't even familiar with bistros.) My boss has become some what of a mentor to me -though I'd never tell her, I don't want to come across as brown-nosing- and since I like doing math in my spare time, I recently found out about linear programming at Purple Math.com (I never heard about it in high school -I'm a freshman in college-)

I was wondering how I could apply it to her business. I already record her receipts into Excell for her and I found on YouTube where Excell has a way to use linear programming. The math itself seems relatively simple, I just need help understanding how I could apply it to help her.

I guess I would need to have a record of how many customers we get, how much food they order, how much time is spent cooking for and serving them, etc. What would I do from there?

Re: Linear Programming help
To apply linear programming, you need an objective function (something to maximise, like profit, or minimise, like costs) and a list of constraints.

In other words, you have to have a problem to apply linear programming to! So far, you are just doing record keeping.

What I'm asking is, what is the second step. What do I do with the information once I have it?

Thank you.

Thank you.

You don't seem to understand what HallsOfIvy and I were saying. We can't tell you what to do with your information, because we don't know what you WANT to do with the information. Like I said, you need to have an objective function - something you want to maximise or minimise...
