A graph shows that a plant grows 2 inches every week. How tall will the plant be after 5 weeks if it was initially 6 inches tall?

• 16 inches

• 10 inches

• 12 inches

• 14 inches

Answer explanation

The plant grows 2 inches every week, so after 5 weeks it will have grown 10 inches (2 inches/week * 5 weeks = 10 inches), making the total height 16 inches (initial 6 inches + 10 inches = 16 inches). Therefore, the correct answer is 16 inches.
