Question

10 inches of snow is equivalent to about one inch of rain. Write an equation for the amount of precipitation, measured in inches of rain, r=f(s), as a function of the number of inches of snow, s.

Answer 1

This is good to know, we get snow here during the winter. Follow the instructions you provided.
r = rain (inches)
s= snow (inches
r = f(s)
r = .1s or f(s)=.1s
