Alexis works part-time at a clothing store. She is paid an hourly rate of $15.25/ h and also earns
a commission of 3.5% of her total weekly sales. Alexis works at the store 12 hours a week.
If Alexis’ goal is to earn $250 every week, what do her total weekly sales need to be?
~~~~~~~~~~~~~~~~~~~
Let x represents her weekly sales.
Then the governing inequality is
250 <= 12*15.25 + 0.035x.
From this inequality find its solution x
x >= = 1914.29.
Her weekly sales should be at least this value.
