Apply the discount first, then add GST to the discounted price.<br><br>
&bull; Discounted price = \(\$2800 \times (100\% - 15\%) = \$2800 \times 0.85 = \$2380\)<br>
&bull; GST = \(8\%\) of discounted price = \(\$2380 \times 0.08 = \$190.40\)<br>
&bull; Final price = \(\$2380 + \$190.40 = \$2570.40\)<br><br>
Final Answer: \(\$2570.40\)
