Step-by-step explanation:
Cost of jacket including tax
[tex] = 83.99 + 83.99 \times \frac{8.25}{100} \\ \\ = 83.99 + 0.0825 \times 83.99 \\ \\ = 83.99 + 6.929175 \\ \\ = 90.919175 \\ \\ \approx \$ 90.92 \\ [/tex]
[tex]\text{Find the total cost of a jacket, including tax.}\\\\\text{We know that the jacket costs \$83.99}\\\\\text{We also know that the subtotal is going to be charged 8.25\% for tax}\\\\\text{To find the total, multiply 83.99 by 1.0825}\\\\83.99*1.0825=90.919\\\\\text{Round to the nearest hundredths:}\\\\\boxed{\$90.92}[/tex]
