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

7s

c=7s

I agree its 7s

Yes but also there is the independent and dependent question you guys didn't answer.

Try looking up what is an independent and dependent variable

To write an equation that relates the cost, c, to the number of student tickets purchased, s, you can use the formula:

c = s * 7

In this equation, s is the independent variable as it represents the number of student tickets purchased. The dependent variable is c, as the cost of tickets depends on the number of tickets purchased.
