【實用工具app】Sales Tax Calculator|最夯免費app-綠色工廠好玩App

This is a very simple to use sales tax calculator that only requires the price and the rate of sales tax usually once. The app would save the sales tax rate for you so you would not need to enter it every time. You then get both the full price and the amount of tax of your item and you are good to go! You can now calculate the tax and total of multiple items!
