--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.

--hints--

getMovieNightCost("Saturday", "10:00pm", 1) should return "$12.00".

assert.equal(getMovieNightCost("Saturday", "10:00pm", 1), "$12.00");

getMovieNightCost("Sunday", "10:00am", 1) should return "$10.00".

assert.equal(getMovieNightCost("Sunday", "10:00am", 1), "$10.00");

getMovieNightCost("Tuesday", "7:20pm", 2) should return "$10.00".

assert.equal(getMovieNightCost("Tuesday", "7:20pm", 2), "$10.00");

getMovieNightCost("Wednesday", "5:40pm", 3) should return "$30.00".

assert.equal(getMovieNightCost("Wednesday", "5:40pm", 3), "$30.00");

getMovieNightCost("Monday", "11:50am", 4) should return "$32.00".

assert.equal(getMovieNightCost("Monday", "11:50am", 4), "$32.00");

getMovieNightCost("Friday", "4:30pm", 5) should return "$50.00".

assert.equal(getMovieNightCost("Friday", "4:30pm", 5), "$50.00");

getMovieNightCost("Tuesday", "11:30am", 1) should return "$5.00".

assert.equal(getMovieNightCost("Tuesday", "11:30am", 1), "$5.00");
