How much did she spend on food during the three months

Answer:
$[tex]$563.20[/tex] or ≈$[tex]563.00[/tex]
Step-by-step explanation
The question states that Mrs. Hadley spent $126.97 on one month, $237.81 on the next, and $198.42 on the last. To get the total, we can add these values together.
[tex]126.97+237.81+198.42=563.20[/tex]
An estimation would be:
[tex]127+238+198=563[/tex]
We can use this estimation to determine that the total value is reasonable.
