Answer:
her new balance is $1,084.99
The mathematical expression will be (2n / n² + 7) - 3.
The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the quantity three is less than twice this number divided by the quantity 7 more than the square of this number.
The required expression will be written as:-
E= (2n / n² + 7) - 3.
Therefore, the mathematical expression will be (2n / n² + 7) - 3.
