How much GST is in $100?

Could you please clarify what GST refers to in this context? Assuming GST stands for Goods and Services Tax, which can vary depending on the country and specific tax regulations, it's important to note that the amount of GST in $100 would depend on the applicable GST rate. For instance, if the GST rate is 10%, then the GST amount in $100 would be $10. However, if the GST rate differs, the calculation would change accordingly. Could you provide more information about the specific GST rate applicable to your situation?
