The jump between 1980 to 2003 will not be factored as theprices have also steadily increased but were not charted. 2003 through 2015, the fare has alsoincreased (bv the given table) by 25 cents.P r i c e i Dcll-a i-s iStep 3: Defining M y VariablesIndependent Variable- X - represents ± e time in years.Dependent Variable- ¥ - represents the cost in dollars.
