Answer:
The Third one
Step-by-step explanation:
Answer:
Given the polynomial: 
Since, arranging of polynomial can be made by forming the given polynomial into the general form.
Multiply the following polynomials are;

Using distributive property: 

Remove the parenthesis; we get;

Combine like terms;

⇒This is the general form of the polynomial equation.
Since, the given polynomials can be written from the order of powers i.e,

To arrange this polynomial in descending order means to arrange the powers of variables in each term in descending order.
Therefore, the resulting polynomial in descending orders is, 
57-10.51=46.49
46.49-8.73=37.76
37.76-8.47=29.29
Therefore Daniel has $29.29 left.
