Question

3. Suppose you are buying a $30 pair of shoes that are discounted 20%. How much will you pay for the shoes?

Answer 1

$24

Explanation:

calculate 20% of $30 and subtract the discount from the cost price

20% =
`(20)/(100)` = 0.2, hence

discount = 0.2 × $30 = $6

buying price = $30 - $6 = $24

Answer 2

$24

Explanation:

To determine the discount, we take the price of the shoes and multiply by the discount rate

Discount = 30 * .2

Discount = 6

The new price is the original price minus the discount

new price = 30-6

New price = 24
