The savings are $71.25


We need to calculate 15% of $475 to see what the savings are:

"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 number we are looking for "n".

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

#n = 15/100 xx $475#

#n = $7125/100#

#n = $71.25#

So the savings are $71.25 which we now must subtract
