Answer:
$1500
Explanation:
First, we determine her commission on sales.
[tex]\begin{gathered} \text{Income}=\text{Salary}+\text{Commision} \\ 275=200+\text{Commision} \\ \text{Commision}=275-200 \\ \text{Commision}=\$75 \end{gathered}[/tex]Since she is paid a 5% commission on her sales this week.
Let her total sales this week = t
[tex]5\%\text{ of t = 75}[/tex]We then solve for t:
[tex]\begin{gathered} \frac{5}{100}\times t=75 \\ t=75\times\frac{100}{5} \\ t=75\times20 \\ t=\$1,500 \end{gathered}[/tex]Her total sales this week is $1,500.
