The cost of a student ticket to the school play is $7. Write an equation that correctly relates the total cost, c, for a particular number, s, of student tickets purchased. Identify the independent and dependent variables.

c = 7s

doesn't the cost c depend on the number of students s ?

To write an equation that relates the total cost, c, for a particular number, s, of student tickets purchased, you need to consider the cost per ticket and the number of tickets purchased.

First, let's identify the independent and dependent variables in this equation. The independent variable is the number of student tickets purchased, denoted as s. The dependent variable is the total cost, denoted as c, which depends on the number of tickets purchased.

The cost per student ticket is given as $7. To find the total cost for a particular number of student tickets purchased, you need to multiply the cost per ticket by the number of tickets. Therefore, the equation can be written as:

c = 7s

In this equation, c represents the total cost, and s represents the number of student tickets purchased. By multiplying the cost per ticket ($7) by the number of tickets (s), you will get the total cost.
