Question

Joyce Flynn, an insurance agent, earned in her first week on the job a commission of $1,800. Her commission percent is 30%. Joyce's total sales for the week were:

Answer 1

Her totals sales were "x", now, if she sold "x", and made a 30% of "x" which is 1800, that simply means, "x" is the 100%

$\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ x&100\\ 1800&30 \end{array}\implies \cfrac{x}{1800}=\cfrac{100}{30}$

solve for "x"
