Respuesta :
They should subtract $ -20 because they went behind on how much they planned to save. Now this question can be tricky because some might say they lost 0 because they already had an extra $20 but it is only asking for the month of February and is only asking for each month not the entire year.
Answer:
-$20
Step-by-step explanation:
We are given that
A family wants to save each month =$100
In January, they saved=$120
They recorded at the end of the month January=+$20
In February, they saved=$80
We have to find that what should they record at the end of month February if the saved $80.
Family wants to save each month=$100
But in February,
The family saved only=$80
Therefore, they recorded at the end of month February=80-100=-$20
Hence, they should record -$20 for the month of February if they saved $80 . Because they did not achieve their target .They have $20 lack from their monthly target.
