Hello everyone.

Michelle - you mentioned a file before - can you attach it?

oh, the file was the writen words on my post. I typed them~~

Hi,

I'm not sure... but will the total money set aside for the Child's Education be 6200??

on the x axis... (6200,0)?

Michelle,

Sorry, but I don't think I'm going to be much help on this one...

Hey everyone,,
does anyone have any possibilities for this problem?
i'm still not getting this..

:eek:

Michelle,

The general strategy with these kinds of problems is to first determine the graphical boundaries, then plot the y vs x relationships.

The budget or boundary (or constraint) would be "y + x = total amount of money available in the budget" where, as y increases (contributions), x decreases (money left over to buy food, etc.), and vice versa.

Then plot the function(s) that describe y = mx + b where x is the amount of money contributed, m is the matching rate + contribution, b would be any "flat" contributions, and then y would be the total return.

These functions are piece-wise and will have "kinks" in them where the matching rate changes.

(See attached graph image for a rough example).

Sorry this is kind of general, but my background in economics is pretty much non-existent.
