Identify the independent and dependent variables. Then write a rule in function notation for the situation, letting x represent the independent variable. A concert ticket costs $60.

independent: number of tickets purchased;

dependent: total cost;

rule: f(x) = 60x

Step-by-step explanation:

The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.

The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.

The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.
