See a solution process below:

Because the problem states #15% color(red)(" off")# we know this is a discount.

To find the amount of the discount we can restate this problem as:

What is 15% of $305?

"Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as #15/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the discount we are looking for "d".

Putting this altogether we can write this equation and solve for #d# while keeping the equation balanced:

#d = 15/100 xx $305#

#d = ($4575)/100#

#d = $45.75#
