Hey Everyone,

I just want to make sure I understand this... When a problem says "greatest possible value" wouldn't they mean ? And when a problem says "minimum number of..." wouldn't that be ? Just need to verify that (Wink).

Thanks.

Here are my problems:

**1.**The length of a rectangle is three times its width. If the perimeter is at most 112 centimeters, what is the greatest possible value for the width? Write an inequality to model the problem.

2*w*+ 2 http://k12highschools.com/ec/pub/K12...pChar/8226.gif (3*w*)http://k12highschools.com/ec/pub/K12...pChar/8805.gif112

2*w*+ 2 http://k12highschools.com/ec/pub/K12...pChar/8226.gif (3*w*) < 112

2*w*+ 2 http://k12highschools.com/ec/pub/K12...pChar/8226.gif (3*w*) > 112

2*w*+ 2 http://k12highschools.com/ec/pub/K12...pChar/8226.gif (3*w*)http://k12highschools.com/ec/pub/K12...pChar/8804.gif112

And:

**2.**Josephine started a business selling cosmetics. She spent $4500 to obtain her merchandise, and it costs her $200 per week for general expenses. She earned $550 per week in sales. What is the minimum number of weeks it will take for Josephine to make a profit? Write an inequality to model the problem.

550*w*> 4500 + 200*w*

200*w*> 4500 + 550*w*

550*w*< 4500 + 200*w*

200*w*http://k12highschools.com/ec/pub/K12...pChar/8805.gif4500 + 550*w*

So for the first problem I think it's the first answer and for the second problem I think it's the third answer. Am I correct? - October 20th 2009, 08:51 AMElectroNerd
