I can't figure out the formula to use for this question. I am looking at Cost per capita, which means per capita costs divided by the population. The population figures are 16,974, 18,698 & 19,151. The actual cost figures are $70,258, $136,304 & 238,041. what type of formula do I use when pop figures are listed in cells b1:b3 and cost figures are listed in A1:A3. Any help would be appriciated.

You walk upwards on an escalator, with a speed of 1 step per second. After 50 steps you are at the end. You turn around and run downwards with a speed of 5 steps per second. After 125 steps you are back at the beginning of the escalator. How many steps do you need if the escalator stands still?

Normal optical filter blocks some range of light frequency. Filter characteristics is static and never changes.

What I'm looking for is a filter with variable characteristics which is sensitive to mechanical force exerted on it. For example, if a filter is stretched outward, its filtering range moves as the strech continues.

Am I dreaming? Looking at the eye glasses that is darkened when you are outside and gets light when inside, hopefully I'm not.
