Answer: 19.26%

Step-by-step explanation:

Given : Van purchased a DVD player on sale.

The initial price was $179.30. The price after the discount was $144.77.

Then, the discounted price = Initial price - Price after the discount

= $179.30-$144.77= $34.53

Now, the percent of decrease is given by :-

[tex]\dfrac{\text{Discount amount}}{\text{Original price}}\times100\\\\=\dfrac{34.53}{179.30}\times100=19.2582264361\approx19.26\ \%[/tex]

Hence, the percent of decrease = 19.26%
