~~~~~~~~~~~~~~~~~~~~
This problem is about solving a compound inequality
700000 <= 496000 + x <= 750000.
To solve it and find x, subtract 496000 from both sides
700000 - 496000 <= x <= 750000 - 496000,
which gives the
ANSWER. She can spend from $204,000 to $254,000 and to be still within her estimate.
Solved.
