Nathan took his car in for service and repairs. He had a coupon for 15% off.

Original Prices

• Labor $266.63

• Parts $317.29

• Other $62.78

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
