Freda is worried about an upcoming vacation she has planned. In the past, the area she is planning to visit has experienced extreme weather conditions. She receives the following advice from her four friends.
Henry: “I think you should postpone your trip. I watched an old documentary about a hurricane that made landfall around the same date that you are scheduled to arrive.”
Ian: “I think you should go ahead with your plans. I read in the most recent edition of the Farmer’s Almanac that this year's hurricane season is not supposed to be that dangerous.”
Julia: “I think you should postpone your trip. I checked the local 3-day weather forecast for the area, and you are scheduled to arrive the same day meteorologists predict the hurricane to make landfall.”
Kelsey: “I think you should go ahead with your plans. About three weeks ago, I watched a news report about this hurricane when it was just developing in the ocean. At the time, scientists predicted the hurricane would lose its energy before making landfall.”

Kim sold 19 pizza kits. Marty sold 28 pizza kits. How many more pizza kits did Marty sell?(1 point)
Marty sold 28 pizza kits, while Kim sold 19 pizza kits.
To find out how many more pizza kits Marty sold, we subtract the number of pizza kits Kim sold from the number of pizza kits Marty sold.
28 - 19 = 9
Therefore, Marty sold 9 more pizza kits than Kim.
The high for Wednesday was −10°, and the low was −23°. How many degrees did the temperature drop on Wednesday?(1 point)
To find out how many degrees the temperature dropped on Wednesday, we need to calculate the difference between the high and low temperatures.
The high temperature was -10° and the low temperature was -23°.
To find the difference, we subtract the low temperature from the high temperature:
-10° - (-23°) = -10° + 23° = 13°
Therefore, the temperature dropped 13 degrees on Wednesday.
Joyce uses the subtraction algorithm to subtract −35−55 and gets the answer −90. She connects this expression and answer to a number line model. Fill in the blanks to explain what is shown in the number line model.

Using a number line, Joyce starts at the point
. She then finds that she needs to move
in the negative direction to get to −35. Therefore, −35−55=
