I'm don't understand the sample. where does the 80 and 50 come from? my desire point is 18 I just need to understand the logic of getting 80 and 50? If the ranges of the original attribute levels for speed and complexity, are 25 to 213 (for speed) and 2.7 to 19.2 (for complexity). Calculate the best attribute levels expressed in their original (unstandardized) scales, for both speed and complexity for both of your new R&Ds and show work

Context: Suppose you want a product that is a "-11" on the -25 to +25 perceptual map scale. Question: What is this "-11" in terms of the attribute units that products are designed to when an R&D is done? Let's call that value "x" in the diagram below: Perceptual scale (-25 to +25) 50 14 -25 -11 0 +25 20 14/50 80 60 100 80 Attribute Units (e.g. 20-100) To get x exactly we interpolate, by starting at 20, and adding the fraction of the overall range: x = 20 + 14/50 * 80 = 42.4
