Question

The original price of a TV was n dollars. How much would it cost in total if the tax was 8.25%?

Answer 1

`\begin{gathered} \text{if the price was n dollars, we have to add the tax of 8.25\% of n, that is} \\ n+n\cdot0.0825=n\mleft(1+0.0825\mright) \\ =n(1.0825) \end{gathered}`

if the price was n dollars, we have to add the tax of 8.25% of n, that is

n+n*0.0825=n(1+0.0825)

=n*(1.0825)
