Answer 1

Some of this problem will require you to design a form. You can use option(radio) buttons, or a textbox for the input of a customer type (number 1 to 4)

after that write a subroutine which accepts an integer (1 to 4) as a customer type and use a select case function to determine the taxrate based upon the customer type entered.


Private Sub myCalculation (cust as integer)

DIM taxrate as double
DIM total as double
DIM tax as double
DIM grandTotal as double


Secect Case cust
case 1
taxrate = .03
case 2
taxrate = .07
case 3

end select


Next get three prices from the user. You can use a For/Next to loop three times . Each time through the loop display an input box to the user asking for a price.

Tootalize the input price

total = total + price

after completing the loop compute the information

tax = total * taxrate
grandtotal = total + tax

then display your results
