Write an inequality to represent the cost of going to a movie is no less than $6.00

We'll use "c" to represent the cost of going to a movie. Make sure you add an annotation explaining that decision. The expression here would be "c ≥ $6.00", because "c" can't cost less than six dollars, but it can cost six dollars exactly. Remember that line underneath the ">", so that your teacher knows you mean to say "greater than or equal to".
