	Lab 5 Problem 5

	This program recieves the day of the week, time a call was placed, and the length of
	the call, then calculates how much the call will cost.

	
	Input (day of week): Mo
	Input (time): 13:00
	Input: (call duration): 24
	Expected Output: Your call will cost $9.60

  	Input (day of week): tU
	Input (time): 1:00
	Input: (call duration): 75
	Expected Output: Your call will cost $18.75

  	Input (day of week): we
	Input (time): 18:00
	Input: (call duration): 10
	Expected Output: Your call will cost $2.50

  	Input (day of week): Th
	Input (time): 7/50
	Input: (call duration): 100
	Expected Output: Your call will cost $25.00

    Input (day of week): fr
	Input (time): 8:00
	Input: (call duration): 30
	Expected Output: Your call will cost $12.00

    Input (day of week): sA
	Input (time): 15:15
	Input: (call duration): 47
	Expected Output: Your call will cost $7.05

	Input (day of week): su
	Input (time): 20:30
	Input: (call duration): 1000
	Expected Output: Your call will cost $150.00

	Input (day of week): SU
	Input (time): 4;20
	Input: (call duration): 75.7
	Expected Output: Your call will cost $11.25

	Input (day of week): Mu
	Expected Output: You entered an invalid day of the week!

	Input (day of week): SU
	Input (time): 15.2
	Expected Output: <who knows>

	Input (day of week): we
	Input (time): 4:20
	Input: (call duration): a
	Expected Output: <who knows>
	
  	
	All of the sample inputs within this test suite were tested and performed as expected.
