Question

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

Answer 1

The percent off on the sale price is 30%.

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,
`(k)/(100)  * 64.99  = 19.5\\\implies k = (19.5 * 100)/(64.99)  = 30`

or, k = 30%

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