Do I include GST on the T2125 for the total cost of the business expense or the subtotal without GST?

[Anonymous]

Need more clarification:

Do I include GST on the T2125 for the total cost of the business expense or the subtotal without GST? My subcontracting business earns less than 30K/yr and I do not collect GST from customers.
Examples:
Vehicle Gas - $100.00 subtotal + GST = $113.00 total including GST. Do I enter $100.00 or $113.00?
Phone Data Expense - $50.00 subtotal + GST = $56.50 total including GST. Do I enter $50.00 or $56.50
