In Saskatchewan where I line there is a pst and a gst so the amount after tax includes them both. Since you live in Alberta where there is no PST the amount paid, $630.67 only includes the ticket price of the item and the 5% gst. If you knew the ticket price, the price before the gst then you would calculate the gst be
which is
Hence the price you paid is
Hence
The difference between the price you paid and the ticket price is the gst. Penny
