Answer:
A sample solution is as follows:
Pseudocode:
start Declarations int custAreaCode int custPhoneInt int calledAreaCode int calledPhoneInt int minutes int price int LOW_RATE = 0.10 int HIGH_RATE = 0.13 int TIME_LIMIT = 20 display “Enter customer area code: ” get custAreaCode display “Enter customer phone
