#$199# is the total price of the MP3 player... which means it's the

#100%# of the player

#15%# off means #100%-15%=85%# of the total value

To find it out multiply

Remember #a%=a/100#

#15%" off of "$199 = $199xx85/100#

Now if you've a calculator.... simply multiply... if you don't

#199=200-1#

#15%" off of "$199 = ($200-$1)xx85/100#

#15%" off of "$199 = $2cancel00xx85/(1cancel00)-$1xx85/100#

#15%" off of "$199 = $170 - ($ 85)/100#

#15%" off of "$199 = 170 - $0.85#

#color(red)(15%" off of "$199 = $169.15#
