Question #9. Using an if/else construct, write a script to calculate the tip of a restaurant bill. Using the command window, ask the user to enter the bill amount. Then ask the user to type if the service was 1) good, 2) average, or 3) bad. 1. If the user typed good, display the bill total including a 20% tip. 2. If the user typed average, display the bill total including an 18% tip. 3. If the user typed bad, display the total including a 15% tip. 4. If the user entered anything other than the three acceptable words, print that the input was invalid and exit the script using a return statement. Be sure your calculated total is formatted as currency (including a dollar sign and precision to two decimal places). Question #10. Rewrite the same restaurant tip script from Question 9, but implement it using a case/switch construct instead of an if/else construct. please answer question #10 using the case/switch instead of if/else
