9)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.
The equation is:
c = 7s
The independent variable is the number of student tickets purchased, s.
The dependent variable is the total cost, c.
To write the equation that relates the total cost, c, for a particular number of student tickets, s, purchased, we can use the formula:
c = 7s
In this equation, "c" represents the total cost, and "s" represents the number of student tickets purchased. The total cost depends on the number of student tickets purchased, making "s" the independent variable, and the total cost, "c", the dependent variable.
