How can you determine the total cost of an item including tax if you know the price of the item and the tax rate?

Percent means partst out of 100 so
x%=x/100

ok so lets say
how to find total
total=how much you spent+(how much you spent times tax percent)
you can use distributive proerty to undistribute the 'how much you spent' (like ba+ac=a(b+c)) to get
total=how much you spent times (1+tax percent)
so what you do is
you know

how much you spent
tax percent so

1. convert tax percent to deceimal
2. plug into foormula
total cost=how much spent times (1+taxindecimalform)

Yeah what do you need help with I'm no girl but ask me anything
