Um... I'm sorry, this question was already answered, but I can back the guy up that he's correct at least? Yeah, I used a calculator and it is 15 ft. I'm sorry if I appear annoying for saying this
-- 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 = <em>20%</em> 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 It checks. <em>yay!
</em>
