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.
2w + 2 (3w)112
2w + 2 (3w) < 112
2w + 2 (3w) > 112
2w + 2 (3w)112
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.
550w > 4500 + 200w
200w > 4500 + 550w
550w < 4500 + 200w
200w4500 + 550w
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?
