Original price - $82. percent of sale price - $65.60

The original price was $82.

-- The dealer knocked ($82 - $65.60) = $16.40 off of the price because
he loves his customers so much and he wanted to make their lives easier.

-- The amount he knocked off is  ( 16.40 / 82 ) = 0.2  =  20% of the original price.



Check:

If he reduced the original price 20%, then 80% of it must have been left.

80% of the original price =  0.8 x $82  =  $65.60

I hoped i help :)

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
