Garima likes her job as a baby-sitter (b), but it pays only Rs300 per hour. She has been offered a job as a tutor (t) that pays Rs600 per hour.

Because of school, her parents only allow her to work a maximum of 15 hours per week, but she needs to make at least Rs6600 per week. Which system of inequalities below correctly models Joann's situation?

• b + t < 15

  3b + 6t > 66

• b + t > 15

  3b + 6t < 66

• 3b + 6t > 15

  b + t < 66

• 300b + 600t < 15

  b + t < 66

Monu and Bala want to improve their yards by planting hostas and ivy. The cost of one hosta is Rs80 and the cost of one pot of ivy is Rs120. They do not want to spend more than Rs600 and they want to buy at least 6 plants. Write a system that represents the possible number of hosta x, and ivy plants y, that could be sold to meet these conditions.

• 8x + 12y ≥ 60

  x + y ≥ 6

• 8x + 12y ≤ 60

  x + y ≥ 6

• 8x + 12y ≤60

  x + y ≤ 6

• 8x + 12y ≥ 60

  x + y ≤6
