Hello, Guys, I am trying to draw a flowchart for my C++ class, but I am having trouble to do it.

Can anyone help me with this problem?

1)Internet Service Provider An Internet service provider has three different subscription packages for its customers: Package A: $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Package C: $19.95 per month unlimited access is provided. Draw a flowchart that calculates a customers monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B, or C. Also, the number of hours used in a month cannot exceed 744. Exit the program if user enters incorrect information
