Which amount is closest to Nathan's total costs after the 15% discount and including 6% sales tax? [Assume tax is applied after the discount is applied.]

Total price = $266.63 + $317.29+62.78=646.7  

Discount = 15%  

Discount amount = (15/100) x 646.7  

=$97.005  

Price after discount = $646.7 - $97.005  

=$549.695  

Sales tax = 6%  

Sales tax amount =(6/100) x $549.695  

=$32.9817

Total cost = Price after discount + sales tax amount

 =$549.695 + $32.9817

 =$582.6767  

=$$582.68

take the top number and divide it by a the bottom number
