In Exercises , formulate the linear or piecewise linear model for the real-life scenario. If a linear model represents a directly proportional Relationship between the independent and dependent variables, so state.

Solid Waste Disposal King County charges $82.50 per ton to dispose of garbage at area transfer stations. A minimum disposal fee of $13.72 per entry is charged for vehicles disposing of trash. In addition to the disposal fee, a moderate risk waste (MRW) fee of $2.61 per ton is assessed. A minimum MRW fee of $ 1 is charged on all transactions.
