  3. $504\$504Cevap
  4. D

Cevap

The correct answer is $504\$504.
The correct final amount is found by first subtracting the discount from the original price, then adding the tax to the new subtotal. A 20%20\% discount on $600\$600 saves $120\$120, making the sale price $480\$480. A 5%5\% tax on $480\$480 adds $24\$24, resulting in a final total of $504\$504.

Adım Adım Çözüm

1
Calculate the amount of the discount.
The discount is $120\$120.
The discount is 20%20\% of the original $600\$600 price (0.20×600=1200.20 \times 600 = 120).
2
Calculate the discounted sale price.
The sale price is $480\$480.
Subtract the discount amount from the original price (600−120=480600 - 120 = 480).
3
Calculate the amount of the sales tax.
The sales tax is $24\$24.
The tax is 5%5\% of the discounted sale price (0.05×480=240.05 \times 480 = 24).
4
Calculate the final total amount.
The final total is $504\$504.
Add the sales tax to the discounted sale price (480+24=504480 + 24 = 504).
