Dorm and Meal Plan Calculator

A University has the following dormitories:

Allen Hall: $1500 per semester
Pike Hall: $1600 per semester
Farthing Hall: $1200 per semester
University Hall: $1800 per semester

The university also offers the following meals plans:

7 meals per week : $560 per semester
14 meals per week: $1095 per semester
Unlimited meals: $1500 per semester

Create an application with the two combo boxes. One should hold the names of the dormitories, and the other should hold the meals plans. The user should select a dormitory and a meal plan, and the application should show the total charges for the semester.

---------------------------------------------------------------------------------------------------------

HERE IS THE EXPECTED OUTPUT

Dorm and Meal Plan Calculator Select a Dorm. University Suites Select a Meal Plan. Unlimited meals per week Calculate Charges Exit Message Total Charges per Semester: $3,300.00 Total charges per semester: $3.300.00 OK
