Given:
Sarah's goal was to save $90 from her paycheck last month.
She was within $12 of that goal.
To find:
The maximum and minimum amounts that Sarah could have saved.
Solution:
Her goal = $90
Difference between actual savings and goal of saving is 12.
Maximum amount = $90 + $12 = $102
Minimum amount = $90 - $12 = $78
Therefore, the maximum and minimum amounts that Sarah could have saved are $102 and $78 respectively.
