Chapter 3.2, Problem 20C

When writing an expression that represents some quantity, we’ll often turn that expression into an equation (or formula, if you like) by using a letter to represent the value of the expression.

How do we know so much about the snow cone business? Because one of us used to own one!

The total cost of selling snow cones is the sum of the variable cost for supplies (which you just found) and the fixed costs: These are costs that aren’t affected by the number of snow cones sold, like rent, insurance, licensing, etc. Look back at the table to find the fixed costs for this business, then use that to write an equation of the form C = _______ that represents the total cost based on x, the number of snow cones sold.
