Question

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

Original Prices
• Labor $269.91
• Parts $381.96
• Other $71.99

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.]
A.
$572
B.
$578
C.
$615
D.
$652

Answer 1

d) $652

Explanation:

The total amount is,

→ $269.91 + $381.96 + $71.99

→ 269.91 + 453.95

→ $723.86

Then the final price will be,

→ ($723.86 - 15%) + 6%

→ (723.86 - (723.86/100) × 15) + 6%

→ (723.86 - 108.579) + 6%

→ 615.281 + (615.281/100) × 6

→ 615.281 + 36.91686

→ 652.19786

→ $652

Hence, the answer is $652.

Answer 2

• Total cost after discount and tax is D) $652

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

Add up the prices

• 269.91 + 381.96 + 71.99 = 723.86

Apply 15% discount

• 723.86 - 15% =
• 723.86*0.85 =
• 615.28

Add 6% tax

• 615.28 + 6% =
• 615.28*1.06 =
• 652.2
