Question

An Internet service provider has three different subscription packages for its customers:

Package A: For $15 per month with 50 hours of access provided.
Additional hours are $2.00 per hour over 50 hours.
Assume usage is recorded in one-hour increments.

Package B: For $20 per month with 100 hours of access provided.
Additional hours are $1.50 per hour over 100 hours.

Package C: For $25 per month with 150 hours access is provided.
   Additional hours are $1.00 per hour over 150 hours
  
Write a program that calculates a customer’s monthly charges.

Input Validation:
1) Be sure the user only selects package A, B, or C; or a, b, or c.
2) The user cannot use more than 720 hrs in a month. (We will assume
a 30-day month for this probkem).

Demonstrate test cases described in table:

Test Case Package Hours
   1       A       50
   2       a       51
   3       B       100      
   4       b       101
   5       C       149
   6       c       251
   7       e       720
   8       c       722

Clearly identify the results of each test case.

{
chrges = hours*15;
cout<<"\nYour monthly charge is: "<<chrges;
}
else
{
temp = hours-50;
hours = hours-temp;

Answer 2

An online video streaming service has three different subscription packages for its customers: Package Lite: For $5 per month 5 hours of access are provided. Additional hours are $3.00 per hour. Package Regular: For $15 per month 30 hours of access are provided. Additional hours are $2.00 per hour. Package Unlimited: For $30 per month unlimited access is provided. Write a program that calculates a customer's monthly bill. It should ask the user to enter the name of the package the customer has purchased (Lite, Regular, or Unlimited) and the number of hours that were used. It should then display the total charges.In addition, calculate and display the amount of money Lite package customers would save if they purchased the regular or unlimited package, and the amount of money Regular customers would save if they purchased the unlimited package. If there would be no savings, no message should be printed.
