Question

If a purchase subtotal is $52.02,what will the final total be after asales tax rate of 4.75% is applied?

Answer 1

$52.02 -----> 100%

x --------------> 4.75%

$\begin{gathered} \frac{100}{4.75}=\frac{52.02}{x} \\ \frac{x100}{4.75}=\frac{52.02}{x}x \\ x=52.02\times\frac{4.75}{100} \\ x=2.47 \end{gathered}$

then the final total is:

$52.02 + $2.47 = $54.49
