Which inequality models this problem?
Eduardo started a business selling sporting goods. He spent $7500 to obtain his merchandise, and it costs him $300 per week for general expenses. He earns $850 per week in sales.
What is the minimum number of weeks it will take for Eduardo to make a profit?
850w≥7500+300w
850w<7500+300w
850w>7500+300w
300w>7500+850w
+1253 #3 is the correct answer.
First of all, the cost should be on one side and the earning on the other.
Eduardo needs to pay 7500 dollars plus 300 dollars a week, or 7500+300w
He earns 850 dollars, or 850w.
Now, we want him to make a profit, so 850w has to be greater than 7500+300w, so #3 is correct.
You are very welcome!
