To determine how close Katie and Emily's bean plants are to the goal of at least 13.5 inches, we need to calculate the difference between their plant heights and the goal height.

  1. For Katie:

    • Katie's plant height: 15.2 inches
    • Goal: 13.5 inches
    • Difference: 15.2 inches - 13.5 inches = 1.7 inches
    • Since 15.2 inches is greater than 13.5 inches, Katie is 1.7 inches over the goal.

  2. For Emily:

    • Emily's plant height: 12.9 inches
    • Goal: 13.5 inches
    • Difference: 12.9 inches - 13.5 inches = -0.6 inches (or 13.5 inches - 12.9 inches = 0.6 inches)
    • Since 12.9 inches is less than 13.5 inches, Emily is 0.6 inches under the goal.

Based on the calculations:

  • Katie is 1.7 inches over the goal.
  • Emily is 0.6 inches under the goal.

Therefore, the correct response is:

Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
