how to ue percents(for a cash register)

[the_scott_mans]

I was just wondering on how to calculate the pecent of somthing for cash register (TAXES)

EX. $28.00 + 15%

[Tony]

you multiply by persantage/100.

if you add persantage then first you find what the persantage is (though multiplying) then you add.

so canadian tax is:

code:

total := subtotal + subtotal*15/100

or you can just use 0.15 which is same as 15/100

do you know how to get it to only add up the choices selected

[Asok]

use a boolean(true/false variable) per specific item to determine what has been selected and what hasn't.

How would i go about doing this? like would i put "get (var)" and have them enter in the numbers and when the number was entered it would be like a true statement.

Do you know a little of the code just an example so i can see how it is done just wondering i think i know what you mean.

[Blade]

code:

var choice:boolean:=false %declare the var as false... make it true later on in your %program, if something happens that makes it true %your code here if choice = false then %do whatever else %do whatever if its true end if

after i have done all that what would i put for the true statement how would i add up the prices
