The cost of tolls on the New Jersey Turnpike is based upon the number of miles traveled on it. If you travel 95miles or less the cost is an initial fee of \$.50 and \$.10 per mile. After 95 miles the cost per mile drops to \$.05 . Determine a function that models the total cost of driving on the Turnpike.

Sketch a graph of the scenario.

Determine my cost if I get on the Turnpike at mile marker 60.5 and get off at 93.4.

Determine the cost to drive the full 112 miles on the Turnpike.

How far can I get on \$2.50.Slide7
