Sales tax 8%
8/100 x $39.50
= $3.16

Textbook price + Sales Tax =
$39.50 + $3.16
=$42.66

Discount 8%
8/100 x $42.66
= $3.4128

Textbook price - Discount
= $42.66 - $3.4128
=$39.2472

Find out the what was the original price of her purchase .

To prove

Let us assume that the original price of her purchase be x.

As given

A store is having a 20%-off sale on all merchandise. If Mai buys one item and saves $13 .

20% is written in the decimal form.

$= \frac{20}{100}$

= 0.20

Than the equation becomes

x × 0.20 = 13

$x = \frac{13}{0.20}$

x = $65

Therefore the original price of her purchase is $65.
