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

#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!
