Question

Caitlin Grasso is a salesperson in the kitchen and bath department at Morris Supplies, Inc. She is guaranteed a minimum salary of $200 per week plus 5.5% of her total sales. What are her total sales for a week in which her gross pay was $560.

Answer 1

Well, from those 560, 200 are from her salary, and the rest is commissions from sales, so.... 360 is the 5.5% she's got, now, if we take "x" to be the 100% for the sales, then

$\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 360&5.5\\ x&100 \end{array}\implies \cfrac{300}{x}=\cfrac{5.5}{100}$

solve for "x".
