Reply to comment by eddy_talon in Costco rotisserie chicken cost effectiveness [OC] by phsource

I don't understand the Y-axis either. It first I thought it was number of chickens, but that didn't really make sense. Logically it's USD but then the graph doesn't make sense. Unless the price is fixed and not per pound but if that's the case... What's the Y-axis? So I think it must be the number of chickens a nd get stuck in my loop all over again.

It's a fixed price per pound with a max price of $5. Hence you get a pair of piecewise linear functions.

Its not fixed, or the blue line would be horizontal across

You must have missed the part about the price maxing out at $5

Just because you contradict yourself in the next half of a sentence doesn't mean the first half is correct. It is not a fixed price per pound.

Also known as not a fixed relationship
