The problem is to write a script that will calculate the cost. I understand that it is a loop problem. I'm lost as to how to define the time. I believe that it has to be converted to 24 hr format to use greater than less than etc.. but any help would be grateful.

Write a program in a script file that calculates the cost of mailing a small package according to the following price schedule:

Type of service

Weight more than 0 kg to 1kg

Weight more than 1 kg to 5kg

Ground

RM1.50

RM1.50+RM0.50 for each kg or fraction of a kg above 1kg.

Air

RM3.00

RM3.00+RM0.90 for each kg or fraction of a kg above 1kg.

Overnight

RM18

RM18.00+RM6.00 for each kg or fraction of a kg above 1kg.

The program asks the user to enter the weight and the type of service. The program then displays the cost. If a weight larger than 5kg is entered a message “Service is not available for packages that weigh more than 5kg” is displayed. Run the program and enter 0.25, 3.2, and 10 kg for Ground and Air service, and 1, 4.1 and 6.5 kg for Overnight service.

Dear Andrew, here is the code for your question:

calltime = input('Enter call time(day, evening, night): ', 's');
callduration = input('Enter call duration: ');
callduration = round(callduration);
AboveThirty = 0;
TentoThirty = 0;
OnetoTen = 0;
TotalCost = 0;
if callduration > 30
    AboveThirty = callduration - 30;
    TentoThirty = 20;
    OnetoTen = 10;
elseif callduration > 10 && callduration <= 30
    TentoThirty = callduration - 10;
    OnetoTen = 10;
else
    OnetoTen = callduration;
end
switch calltime
    case 'day'
        OnetoTen  = OnetoTen * 0.1;
        if TentoThirty ~= 0
            TentoThirty = TentoThirty * 0.08 + 1;
        end
        if AboveThirty ~= 0
            AboveThirty = AboveThirty * 0.06 + 2.6;
        end
        TotalCost = OnetoTen + TentoThirty + AboveThirty;
    case 'evening'
        OnetoTen  = OnetoTen * 0.07;
        if TentoThirty ~= 0
            TentoThirty = TentoThirty * 0.05 + 0.7;
        end
        if AboveThirty ~= 0
            AboveThirty = AboveThirty * 0.04 + 1.7;
        end
        TotalCost = OnetoTen + TentoThirty + AboveThirty;
    case 'night'
        OnetoTen  = OnetoTen * 0.4;
        if TentoThirty ~= 0
            TentoThirty = TentoThirty * 0.03 + 0.4;
        end
        if AboveThirty ~= 0
            AboveThirty = AboveThirty * 0.02 + 1;
        end
        TotalCost = OnetoTen + TentoThirty + AboveThirty;
    otherwise
        disp('Invalid call time')
end
fprintf('Call cost is: %f\n', TotalCost)
