# Using Functions with Variation

I have a story problem that involves using variation and functions, and I don't even know where to begin or how to read this problem. Could you walk through setting it up and solving it please! Thank you very much!

(Problem 42 is an example of the golden ratio, or phi, a proportionality constant that appears in nature. The numerical approximate value of phi is 1.618. From www.goldenratio.net.

42. Human Anatomy
Each section of your index finger, from the tip to the base of the wrist, in larger than the preceding one by about the golden (Fibonacci) ratio. Find an equation that represents the ratio of each section of your finger related to the previous one if one section is 8 units long and the next section is 5 units long.
