Question 11

Case 1 - BrainPower Tutoring
The owner of BrainPower Tutoring needs an application to calculate and print estimates to provide to potential clients for tutoring services. A tutoring session is a minimum of one hour, and the hourly rate varies based on the subject. The application should allow the owner to enter the client’s name, subject, number of tutoring sessions, and hourly rate. The application will display the total fee and allow the owner to print the estimate. You should also provide the ability for the owner to clear the screen and exit the application.
-Which of the following statements would calculate and display the total fee?

Accepted Answer

This statement correctly converts the input values of txtNumberSessions and txtRate into numbers using Val(), multiplies them together, and assigns the result to the lblTotalFee control. Option A also correctly calculates the total fee, but it assigns the result to a control called TotalFee.Text, which may not exist in the program. Option B multiplies the text values of NumberSessions and Rate without converting them to numbers first. Option D multiplies the variable names NumberSessions and Rate without indicating where the result should be displayed.

Question 14

Case 1 - BrainPower Tutoring
The owner of BrainPower Tutoring needs an application to calculate and print estimates to provide to potential clients for tutoring services. A tutoring session is a minimum of one hour, and the hourly rate varies based on the subject. The application should allow the owner to enter the client’s name, subject, number of tutoring sessions, and hourly rate. The application will display the total fee and allow the owner to print the estimate. You should also provide the ability for the owner to clear the screen and exit the application.
-Which of the following statements is true about printing the estimate?

Accepted Answer

The statement mentions the option of sending the estimate directly to the printer or a PrintPreview window, indicating that the printing process requires some specification. Option B is incorrect as the statement does not mention the PrintForm tool. Option C is incorrect as it implies that the whole printing task can be accomplished with a single code statement, which is unlikely. Option D is also incorrect as there are ways to hide certain elements on a form during printing, so it is not true that the buttons must appear on the printed estimate.
