--description--

Given a string for the day of the week, another string for a showtime, and an integer number of tickets, return the total cost of the movie tickets for that showing.

The given day will be one of:

  • "Monday"
  • "Tuesday"
  • "Wednesday"
  • "Thursday"
  • "Friday"
  • "Saturday"
  • "Sunday"

The showtime will be given in the format "H:MMam" or "H:MMpm". For example "10:00am" or "10:00pm".

Return the total cost in the format "$D.CC" using these rules:

  • Weekend (Friday - Sunday): $12.00 per ticket.
  • Weekday (Monday - Thursday): $10.00 per ticket.
  • Matinee (before 5:00pm): subtract $2.00 per ticket (except on Tuesdays).
  • Tuesdays: all tickets are $5.00 each.
