Let’s solve each problem one by one, step by step. We’ll use simple math and think about what’s happening in each situation.

Problem 1: Julian’s Temperature Change
Julian is moving from Sedona (hottest = 112°F) to Juneau (hottest = 72°F).
We want to find the temperature change he will experience.
Since he’s going from a hotter place to a cooler place, the temperature will go down.
So we subtract:
112 - 72 = 40
That means the temperature drops by 40 degrees.
But since it’s a *change*, and it’s getting colder, we can say the change is
-40 degrees F.
✔ Final Answer for #1:
-40 degrees F

Problem 2: Abraham’s Pool to Jacuzzi
Abraham goes from pool (62°F) to Jacuzzi (113°F).
He’s going from cold to hot — so temperature increases.
Subtract:
113 - 62 = 51
So the temperature change is
+51 degrees F.
✔ Final Answer for #2:
+51 degrees F

Problem 3: Zack’s Report Grade
Zack got 93, but loses 15 points for being late.
So we subtract:
93 - 15 = 78
His final score is 78.
✔ Final Answer for #3:
78

Problem 4: Taylor’s Money Lost
Taylor lost money over several days:
- Monday: lost $20 → that’s -20
- Tuesday: lost $5 → that’s -5
- Wednesday: no loss → 0
- Thursday: lost $7 → that’s -7
Total lost = 20 + 5 + 7 = 32 dollars
He lost all his savings, so before playing, he had exactly $32.
✔ Final Answer for #4:
$32

Problem 5: Imani’s Bank Account
Imani’s account was at -$43 (she overspent).
Then she wrote another check for $50 → that takes away more money.
So we add the two negatives:
-43 + (-50) = -93
Her new balance is -$93.
✔ Final Answer for #5:
-$93

Final Answer:
1) -40 degrees F
2) +51 degrees F
3) 78
4) $32
5) -$93
