Answer:

The sale price of the item is #$255#.

Explanation:

To determine the amount of discount (#d#) offered by the store, we calculate #15%# of the sale price. Thus:

#d=300xx15/100#

#d=3cancel(00)xx15/(1cancel(00))#

#d=3xx15#

#d=45#

If the amount of discount is known, the sale price (#s#) of the item will be the regular price minus the discount. Hence:

#s=300-45#

#s=255#
