Concept explainers
Highway tolls. It has been suggested that since heavier vehicles are responsible for more wear and tear on highways, drivers should pay tolls in direct proportion to the weight of their vehicles. Suppose a Toyota Camry weighting 3350 lb was charged $2.70 for traveling an 80-mile stretch of highway
a. Find an equation of variation that expresses the amount of the toll T as a function of the vehicle's weight w.
b. What would the toll be if a 3700-lb Jeep Cherokee drove the same stretch of highway?
