Answer:
$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.
