Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $26 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has a $15 monthly fee and charges an additional $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

For communication, Sonia uses a satellite phone that costs ₹10.25 per minute. If she talks to Mission Control for 15.6 minutes each day, how much will her total communication cost be for the entire mission?

Write a program that calculates the bill for a cellular telephone company. The company offers two types of service: regular and premium. Its rates vary depending on the type of service. The rates are computed as follows:·         Regular Service: R100 + The first 50 mins are free + R2 per minute for mins over 50.·         Premium Service:  R250 +a.       For calls from 6:00 a.m. to 6:00 p.m., the first 75 minutes are free; charges for more than 75 minutes are R1 per minute.b.      For calls from 6:00 p.m. to 6:00 a.m., the first 100 minutes are free; charges for more than 100 minutes are R0.5 per minute.Your program should prompt the user to enter an account number, a service code, and the number of minutes the service was used. A service code of r or R means regular service; a service code of p or P means premium service. Treat any other character as an error.For the premium service, the customer may use the service during the day and the night. Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night.  Your program should then generate an invoice by writing the account number, type of service, number of minutes the telephone service was used, and the amount due to a file called bill.txt.

Write an expression for the total cost (in dollars) of a call lasting t𝑡 minutes.

Rahul manages a car service facility and wants to calculate the service charges for cars based on the time they have spent at the facility. The program takes the number of cars 'n' and the hours each car has been at the facility. It then calculates the service charges according to specific conditions and displays the car number, hours of service, and the corresponding charges for each car. Rahul uses this program to efficiently manage his car service operations.Up to 3 hours: Rs. 30.0Beyond 3 hours: Rs. 30.0 + (hours - 3) * Rs. 5.0Exactly 24 hours: Rs. 80.0Input format :The first line consists of an integer n, representing the number of cars.The next n lines consists of two integers, representing the car number and the number of hours that the respective car has spent at the facility.Output format :For each car, the output displays three values separated by spaces, representing the car number, the hours of service, and the corresponding service charges. The charges should be displayed in two decimal places.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:2 ≤ n ≤ 101 ≤ hours ≤ 24Sample test cases :Input 1 :31867 35382 52407 24Output 1 :1867 3 30.005382 5 40.002407 24 80.00Input 2 :23245 17851 15Output 2 :3245 1 30.007851 15 90.00Input 3 :101234 41245 81456 107896 231111 122244 153247 201478 61498 103457 24Output 3 :1234 4 35.001245 8 55.001456 10 65.007896 23 130.001111 12 75.002244 15 90.003247 20 115.001478 6 45.001498 10 65.003457 24 80.00Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.Marks : 10Negative Marks : 0
