Question

A family wants to save $100 each month. They record their progress toward this goal at the end of each month. In January they saved $120 and recorded +$20 at the end of the month. What should they record for the month of February if they only saved $80 that month? Explain.

Answer 1

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 2

-$20

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.
