Backpack is normally $64.99, put on sale it is marked down to $45.49 what percent off is the sale price
pogonyaev

Answer:

The percent off on the sale price is 30%.

Step-by-step explanation:

Marked up price = $64.99

marked down Price = $45.49

Let us assume the off percentage = k%

Now, the Amount off on the sale = Marked up price - Marked down price

                                                        = $64.99 -  $45.49  = $19.5

⇒  k% off on Marked up Price  $64.99 = $19.5

or, \frac{k}{100}  \times 64.99  = 19.5\\\implies k = \frac{19.5 \times 100}{64.99}  = 30

or, k = 30%

Hence, the percent off on the sale price is 30%
