Question

jasmine plans to take a short vacation in two weeks. Before her vacation, she wants to earn more than $700 each week. The store where she works pays her $500 per week plus 5% of her sales for that week. How much in sales, s, does she need to make each week to meet her goal? Write and solve an inequality to answer this question.

Answer 1

Y = Earnings per week

X = Sales per week

5% = 1/20

---------------

Y = 500 + 1/20 * X

----------------

500 + 1/20 * X > 700

1/20 * X  > 700 - 500

1/20 * X > 200

20 * 1/20 * X > 200 * 20

X > 4000

--------------

Jasmine needs to make over $4,000 in sales each week to meet her target.
