holeyness Posted January 5, 2012 Report Share Posted January 5, 2012 Yes, you initially assume the gas station a is $1, and b is $.98 like in the question. You can adjust the price later using graph to compare a 2% saving. Reply Link to post Share on other sites More sharing options...
strawberry.paradise Posted January 5, 2012 Report Share Posted January 5, 2012 Yup. Notice that it says Arwa's vehicle and Bao's vehicle. Did anyone get to the last point yet? Reply Link to post Share on other sites More sharing options...
3.1415 Posted January 6, 2012 Report Share Posted January 6, 2012 The last bullet is asking to account for time. How would I approach modifying the model to account for time? Thank you. Reply Link to post Share on other sites More sharing options...
holeyness Posted January 6, 2012 Report Share Posted January 6, 2012 Think about how long it would take to fill up the gas at the extra distance, and consider if its worth it. Reply Link to post Share on other sites More sharing options...
Beccah Posted January 6, 2012 Report Share Posted January 6, 2012 for "write a model that helps motorists decide on the more economical option for their vehicles" what does that mean? is it an equation or something else? Reply Link to post Share on other sites More sharing options...

3.1415 Posted January 7, 2012 Report Share Posted January 7, 2012 For last bullet, do you consider highway versus local road? Reply Link to post Share on other sites More sharing options...

puglover Posted January 9, 2012 Report Share Posted January 9, 2012 what does your effective liter equation look like? and the equations for the graphs? Reply Link to post Share on other sites More sharing options...
holeyness Posted January 10, 2012 Report Share Posted January 10, 2012 what does your effective liter equation look like? and the equations for the graphs?I don't think we can share that, it's not that hard to deduct for yourself. Reply Link to post Share on other sites More sharing options...
jgross1 Posted January 29, 2012 Report Share Posted January 29, 2012 Two find the maximum distance that Bao should drive and save 2%, we need to look at the cost per effective liter in each option. But my question is, once you have the model, E2 has to be 0.98E1, right? Reply Link to post Share on other sites More sharing options...
holeyness Posted January 30, 2012 Report Share Posted January 30, 2012 Nope, that's incorrect. Maybe it is for the first time, but the E2 takes account into the extra distance, plus it's not always 0.98 Reply Link to post Share on other sites More sharing options...
Evgeny Dimitrov Posted February 4, 2012 Report Share Posted February 4, 2012 Hello, I have the following question regarding the family of curves of the vehicle of Arwa and Bao. Do we just have to draw some possible routes with different lengths and just give some backup analysis or what? Thank you in advance. Reply Link to post Share on other sites More sharing options...
holeyness Posted February 5, 2012 Report Share Posted February 5, 2012 yes, you think of different lengths Reply Link to post Share on other sites More sharing options...
Evgeny Dimitrov Posted February 5, 2012 Report Share Posted February 5, 2012 yes, you think of different lengths But can you tell me what program did you use and did you actually create functions so that the program could make these paths and did you limit any ranges or smth. like that. Because I don't think it is necessary to create the drawings of these paths with functions, or is it? Then I think it gets too complicated.

awesomejenna Posted February 11, 2012 Report Share Posted February 11, 2012 hi guys, i'm actually struggling with the first 3 bullets. If we are given the p1 and p2, what are we supposed to calculate? and also, i was a little confused about what the routes look like. Is the normal route straight? Where is the petrol station placed at? Is there a destination the cars are heading to? Please clarify I am so lost as to what the scenario is Reply Link to post Share on other sites More sharing options...
Tai Nguyen Posted February 25, 2012 Report Share Posted February 25, 2012 So for the parameter is choosing the choices of the vehicle? It's the first bullet btw Reply Link to post Share on other sites More sharing options...
holeyness Posted February 26, 2012 Report Share Posted February 26, 2012 yeah you can choose whatever parameters you like. Reply Link to post Share on other sites More sharing options...
mollipop24 Posted February 26, 2012 Report Share Posted February 26, 2012 Can anyone help with part 2 bullet 2? I don't understand what sort of model I'm supposed to create. Reply Link to post Share on other sites More sharing options...
Flamefighta Posted February 29, 2012 Report Share Posted February 29, 2012 Hi all, just want to clear this up. This portfolio is written in such a way that nearly everyone should have completely different methods/variables/parameters to work this out right?Which means that each and every one of us should most possibly have a different amount of variables right? I have just started this IA today and I found myself facing at least 10 variables (including initial values suggested) whilst trying to figure out "Which motorist is getting the better deal?". Since I determine my own variables I found that in my case Bao's journey costs more than Arwa. Am I right in saying everyone would get a different answer to this bullet point since everyone determines their own variables? By the looks of it it seems there is no right or wrong answer as long as you justify every step you've taken. Reply Link to post Share on other sites More sharing options...
