Answer:

In C++:

#include <iostream>

using namespace std;

int main(){

   int hour; char pkg; float bill = 0;

   cout<<"Package: "; cin>>pkg;

   cout<<"Hour: "; cin>>hour;

   if(hour<=744 && hour >=0){

       switch (pkg) {

           case 'A':

               bill = hour * 9.95;

               if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}

           break;

           case 'B':

               bill = hour * 14.5;

               if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}

           break;

           

           case 'C':

               bill = 19.95;

           break;

           

           default:

               cout << "Package must be A, B or C";}

cout<<"Total Bills: $"<<bill; }

else{ cout<<"Hour must be 0 - 744"; }

return 0;

}

Explanation:

This declares all variables:    int hour; char pkg; float bill=0;

This prompts the user for package type:  cout<<"Package: "; cin>>pkg;

This prompts the user for number of hours:    cout<<"Hour: "; cin>>hour;

This checks if hour is between 0 and 744 (inclusive)

   if(hour<=744 && hour >=0){

If true, the following is executed

A switch statement to check valid input for package

       switch (pkg) {

For 'A' package

           case 'A':

Calculate the bill

<em>                bill = hour * 9.95;</em>

<em>                if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}</em>

End of A package:            break;

For 'B' package

           case 'B':

Calculate the bill

<em>                bill = hour * 14.5;</em>

<em>                if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}</em>

End of B package:<em>            </em>break;

For C package            

           case 'C':

Calculate bill:                bill = 19.95;

End of C package:            break;

If package is not A, or B or C

           default:

Prompt the user for valid package                cout << "Package must be A, B or C";}

Print total bills: cout<<"Total Bills: $"<<bill; }

If hour is not 0 to 744: <em>else{ cout<<"Hour must be 0 - 744"; }</em>

When youre working with a word processing document and you press the Del key what happens
REY [17]
Typically, "Del" stands for "delete."
Most times, this key will do different things depending on the type of keyboard/computer you have. For example, on macs, the "delete" key is also the backspace key, so it will delete the last character you typed. However, on most pcs, the "delete" key will delete characters you typed that are in front of your cursor.
