Write an algebraic expression. Tell

what the variable represents.

Callie paid money to the kennel to
board her cat for 13 days.

t=13c

t=total
c=cost per day

Let's represent the amount of money Callie paid to the kennel to board her cat for 13 days with the variable "M".

So, the algebraic expression is "M". The variable "M" represents the amount of money Callie paid to the kennel.

The algebraic expression would be:

13x

In this expression, the variable "x" represents the amount of money Callie paid to the kennel to board her cat for one day.
