2. sally buys a hand bag. there was a discount of 30%. if sally paid $20, what was the original price?

the original price is $28.57

$20 / 70% = $28.57 original price.

Since the handbag was has discount of 30%, we multiply the original price with the 30% to get the discount value.

$28.57 * 30% = $8.57 discount

To check: deduct the discount from the original price to get the discounted price.

$28.57 - $8.57 = $20
