A cell phone provider has three different subscription packages for its customers:

Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.

Package B: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.

Package C: For $19.95 per unlimited access is provided.

Write a program to ask which package the customer has purchased, what month they are using and how many hours were used.

Determine maxHours. Months with 30 days have 720 hours, and months with 31 days have 744 hours. February, with 28 days, has 672 hours.
