Question

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.]

Answer 1

$582.68

Explanation:

Total amount will be,

→ $266.63 + $317.29 + $62.78

→ 266.63 + 380.07

→ $646.7

Then the final price will be,

→ ($646.7 - 15%) + 6%

→ (646.7 - (646.7/100) × 15) + 6%

→ (646.7 - 97.005) + 6%

→ 549.695 + (549.695/100) × 6

→ 549.695 + 32.9817

→ 582.6767

→ $582.68

Hence, the answer is $582.68.

Answer 2

• Total cost after discount and tax is $582.68

---------------------------------

Add up the prices

• 266.63 + 317.29 + 62.78 = 646.70

Apply 15% discount

• 646.70 - 15% =
• 646.70*0.85 =
• 549.70

Add 6% tax

• 549.70 + 6% =
• 549.70*1.06 =
• 582.68
