Step-by-step explanation:

You cannot simplify this question anymore, for it is already a whole number.

Steps:

-3/1

Eliminate the fraction bar and one...

-3

(Anything over one, is whole...so if I were to put 98384743/1, it would just be 98384743.)

Rick is going to buy donuts for his family. Each donut costs $1.25. If the number of donuts Rick buys is represented using the l

Strike441 [17]

The algebraic expression that represents the total cost would be: A. 1.25r.

<h3>How to Write an Algebraic Expression?</h3>

Given that the number of donuts Rick buys for his family is represented by letter "r", and we also know that:

cost of each donut = $1.25.

Using an algebraic expression, we can create a mathematical expression that shows the total cost for Rick to by a given number of donuts for his family.

Thus:

1 donut = 1.25

r donuts would cost: 1.25 × r = 1.25r.

Therefore, the algebraic expression that represents the total cost would be: A. 1.25r.
