C# coding: How would I code this problem please ?

A car rental agency charges $29.99 per day and 35 cents per mile with a standard rental fee of $1.75. Assume that the user will not enter non-numeric data, so you're welcome to use one of the Parse() or Convert methods. You may, however, use TryParse() if you prefer. Example output: ** PROBLEM 2 *** Enter number of days: 0 Invalid number of days. Please re-enter. Enter number of days: 10 Enter number of miles: -50 Invalid number of miles. Please re-enter. Enter number of miles: 100 Car rental at $29.99 per day for 10 days is $299.90 Mileage at $0.35 per mile for 100 miles is $35.00 Total cost including a fee of $1.75 is $336.65
