1,285 feet
1,285 feet
−1,535 feet
negative 1,535 feet
−1,285 feet
negative 1,285 feet
−1,335 feet
To find the new elevation, we need to calculate the sum of -1,410 feet and 125 feet.
-1,410 feet + 125 feet = -1,285 feet
Therefore, your new elevation is -1,285 feet.

−$28.53
To find the remaining money, we need to subtract the amount Reem owes her friend from her earnings.
$43.78 - $15.25 = $28.53
Therefore, Reem has $28.53 remaining.
The correct interpretation of the sum 56.80 + (-40) = 16.80 in the context of the problem is:
$16.80 is the amount Zuri has left from their earnings last week after purchasing the video game.
To arrive at this answer, you need to understand the concept of addition and subtraction with positive and negative numbers.
- Zuri earned $56.80 at their job last week.
- They spent $40 on a video game, which means a subtraction of $40 from their earnings.
- Adding a positive number (earnings) and subtracting a negative number (expenses) is equivalent to adding both numbers together.
So, 56.80 + (-40) = 16.80 represents the remaining amount Zuri has after subtracting their expenses. In this case, Zuri has $16.80 left from their earnings last week after purchasing the video game.
