Megabyte Energy Bars Question

• Single Megabyte bar: £1.25
• Megabyte Sixpack (6 bars): £5
• 10% Discount given on all orders of £20 or more!
• If the cost calculated after applying the discount involves a fractional number of pennies, the cost will be rounded down to the nearest lower amount that can be paid in pounds and whole pennies.

Examples

Num Bars (input)	Cost in £s (output)	Cost Breakdown
3	3.75	3 single bars
12	10	2 six packs
15	13.75	2 sixpacks and 3 single bars
26	20.25	4 sixpacks, 2 singles (22.50), 10% discount (-2.25).

Notes:

• You may assume that the user types in a positive whole number for the input.
• Remember that the value returned by an input command in Python is alway a string; so you will have to convert the input string into an integer value.
• Your output should be a number (either int or float but not a string) and should be the value of the last argument of the last print statement of your program.

  For this and all questions in this coursework you should not change the input commands or the final print command otherwise our semi-automated marking procedure will not work correctly and you may lose marks.
