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.

Answer 1

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)
Responses

$5.00

$5.13

$14.87

$6.13

Answer 3

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
