Answer:
The amount that was left is;
[tex]\text{ \$307.20}[/tex]Explanation:
Given that;
Brianna worked 48 hours at $8 a hour.
The total earnings for the eek is;
[tex]\begin{gathered} T=\text{time }\times rate=48\times\text{ \$8} \\ T=\text{ \$384} \end{gathered}[/tex]Since taxes were 20%, the amount on taxes is;
[tex]\text{taxes}=20\text{\% of T}=\frac{20}{100}\times\text{ \$384}=\text{ \$76.8}[/tex]The amount that would be left after taxes is;
[tex]\begin{gathered} \text{ \$384}-\text{ \$76.8} \\ =\text{ \$307.20} \end{gathered}[/tex]Therefore, the amount that was left is;
[tex]\text{ \$307.20}[/tex]
