I’ve come across this problem before—what the problem really is is the inappropriate use of proportional savings ($5 is a higher proportion of $15 than of $125) when the attention should be on the absolute savings ($5 in either case) because of the way the problem was framed. The way the problem was presented in this post actually obscures this point.

What use of proportional / absolute savings exactly is appropriate? Can you be more specific in which point is obscured by the framing?
