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
Independent variable: s (number of student tickets purchased)
Dependent variable: c (total cost)
The equation that relates the total cost, c, for a particular number, s, of student tickets purchased can be written as:
c = 7s
In this equation:
- "c" represents the total cost, which is the dependent variable because it depends on the number of student tickets purchased.
- "s" represents the number of student tickets purchased, which is the independent variable because it is not dependent on any other variable.
