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.

Equation:

c = s × 7

Step-by-step explanation:

If the cost of the school play is $7, then the equation would be:

c = s × 7

If any amount of people show up to the school play, the number of people will be s, multiplying by 7 to get the total cost of c.

(For an example, if a family of 6 showed up to the school play, then the total cost would be $42.

In this equation, s = 6 and c = 42.)

Dependent variable: s

Independent variable: c

5x+10 is the correct one

hope this
