This problem seems to be an optimization problem but I don't know how to tackle it since it gives no functions.

Thanks for any help!

This doesn't appear to me to be an optimization problem. You are given information to write 2 linear equations in 2 variables.

I agree, this is not an optimization problem. EDIT: Well, I guess you could consider the task to be optimizing the distance Agatha can travel first class.

I'll get you started, though:

Let distance, in km, traveled first class.

Let distance, in km, traveled second class.

Your two equations are:

Now, how can you relate these two equations to each other? - Nov 4th 2012, 10:39 PMkingsolomonsgraveRe: optimization problem with no function
and then i solved for y in the first equation and got which I then plugged in to the second forumla and solved for x=1050, which, I think, is the number of kilometers the traveller would ride first class, is that right?

Yes, so how many km will she travel in second class?

- Nov 5th 2012, 07:18 PMkingsolomonsgraveRe: optimization problem with no function
it would be 1500-1050=450 I think

Yes, that's correct.
