Solve the following problem using addition and subtraction. Katie and Emily are growing bean plants in their scouting troop. Katie’s bean plant is 15.2 inches tall, and Emily’s is 12.9 inches tall. Their scout leader said that she expected the plants to be at least 13.5 inches by this time. How close are Katie and Emily to this goal?(1 point)
Responses
Both Katie and Emily did not meet the goal.
Both Katie and Emily met the goal.
Katie is 0.6 inches over the goal, and Emily is 1.7 inches under the goal.
Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
To find out how close Katie and Emily are to the goal, we subtract the expected height from their respective plant heights:
For Katie: 15.2 inches - 13.5 inches = 1.7 inches over the goal
For Emily: 12.9 inches - 13.5 inches = 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.
Frida went to the store to buy some things for her trip. Her mom gave her $20 to spend. Frida bought sunscreen for $7.99, toothpaste for $4.59, and a pack of gum for $2.29. Her mom asked for the change when Frida got home. If there was no tax on the items, how much change does she owe her mom?(1 point)

$5.00
$5.13
$14.87
$6.13
To find out how much change Frida owes her mom, we must subtract the total cost of the items from the amount of money her mom gave her:
Total cost of items = $7.99 + $4.59 + $2.29 = $14.87
Change owed to her mom = $20.00 - $14.87 = $5.13
Therefore, the correct response is: $5.13
To find out how close Katie and Emily are to the goal, we can subtract the height of their bean plants from the expected height of 13.5 inches.
For Katie:
13.5 inches - 15.2 inches = -1.7 inches
For Emily:
13.5 inches - 12.9 inches = 0.6 inches
Therefore, Katie is 1.7 inches under the goal, and Emily is 0.6 inches over the goal. So the correct response is: Katie is 1.7 inches under the goal, and Emily is 0.6 inches over the goal.
To solve this problem using addition and subtraction, we need to compare the height of Katie's and Emily's bean plants to the goal of 13.5 inches.
First, let's find out how much taller Katie's plant is compared to the goal. We subtract the goal height (13.5 inches) from Katie's plant height (15.2 inches):
15.2 inches - 13.5 inches = 1.7 inches
So, Katie's plant is 1.7 inches taller than the goal.
Next, let's find out how much shorter Emily's plant is compared to the goal. We subtract Emily's plant height (12.9 inches) from the goal height (13.5 inches):
13.5 inches - 12.9 inches = 0.6 inches
Therefore, Emily's plant is 0.6 inches shorter than the goal.
Based on these calculations, we can conclude that Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal. So, the correct answer is: Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
