Answer 2

Why do you think so

Answer 3

I apologize if my previous response was not clear. As an AI language model, I do not have the capability to directly analyze the source of the answer. However, based on the formatting and structure of the provided expressions, it is typical for AI models to generate equations or formulas in a similar manner. The use of variables (such as D) and arithmetic operations, along with parentheses to indicate order of operations, is commonly seen in AI-generated answers for mathematical expressions.

Answer 4

What does the expression 0.90 (D -5) refer to how do you know and how else can this expression be written

Answer 5

The expression 0.90(D - 5) refers to the amount of money saved by applying a discount on a quantity represented by D.

To understand this, we can break down the expression. (D - 5) represents the original quantity decreased by 5 units. Then, 0.90 is multiplied by the resulting value to calculate the discount, where 0.90 represents a 10% discount (as 1.0 - 0.10 = 0.90).

The expression could also be written as 0.9D - 4.5 in an expanded form, where the constant term (-5) is distributed across the multiplication and simplified to -4.5.
