Question

A dress has a regular price of $100. In September, it is marked down to 20%. In October, it is marked down another 20%. What is the price of the dress in October?

$64.00
$144.40
$140.00
$60.00

Answer 1

$64

Explanation:

$100 - 20%×$100 =

= $100 - 20×$100/100

= $100 - $20

= $80

$80 - 20%×$80 =

= $80 - 20×$80/100

= $80 - 2×$8

= $80 - $16

= $64
