The cost of a small cup of coffee at a deli is $3.50. You can use the equation
t = 3.5n , where t represents the total money made from the sale of small coffees and n is the number of cups of small coffees sold. In this equation, which describes the role of n?

The variable n represents the number of cups of small coffees sold. It is the independent variable because it can be varied or changed, and the corresponding total revenue obtained from the sale of those cups is dependent on the number of cups sold.
