Miles of road cleared of snow equation

Question

The number of miles s of roads cleared of snow is approximated by the model

s(ℎ) = 25 − ((13ln (h/12))/ln(3))

,-(+) , 2 ≤ ℎ ≤ 15 where h is the depth of snow in inches. Use the model to

find s when h = 9 inches. (Show work and round to tenths)

Answer 1

s(ℎ) = 25 − ((13ln (h/12))/ln(3))

s(9)=25 - ((13ln (9/12))/ln(3))=25-((13ln (0.75))/ln(3))=25-(-3.4)=28.4
