Construct a graph model for the following scenario: This is the neighborhood that an icecream vendor visits with her truck once a week. She starts her route at P and ends at A once she finishes her tour. (a) Draw a graph model in the space next to the map or on a piece of paper. (b) Mark any odd degree vertex. (c) Does your graph model has an Euler Path? Explain your answer. You do not need to find the route
