write an algebraic expression: the total cost of x containers of yogurt at $0.79 each?

.79x

79*

The algebraic expression for the total cost of x containers of yogurt at $0.79 each can be written as:

0.79x

To write an algebraic expression for the total cost of x containers of yogurt at $0.79 each, we need to multiply the number of containers (x) by the cost per container ($0.79).

The algebraic expression would be:
Total Cost = x * $0.79

In this expression, x represents the number of containers and $0.79 represents the cost per container.
