To solve the word problem, the critical piece of information you need is the amount of money Sally had when she went to the City Market ($32.00) and the amount she had when she left ($23.05). This allows you to calculate how much she spent on food.
The calculation is as follows: Amount spent = Amount brought - Amount left = $32.00 - $23.05.
Thus, the additional details about what she bought or where she went are not necessary for solving the problem.
