Answer:
$21
Step-by-step explanation:
Original price of sandal = $30
Discount = 30%
What is the new cost of sandals after the discount?
Amount of discount = discount × original price
= 30% × $30
= 30 / 100 × 30
= 9
Amount of discount = $9
New price of sandal = Old price - amount of discount
= $30 - $9
= $21
New price of sandal = $21
