Answer:
The independent variable is s
The dependent variable is c
Explanation:
Identify the independent and dependent variables:
The equation c = 0.09s gives the amount c (in dollars) of commission a salesperson receives for making a sale of s dollars.
c = 0.09s
Where
c = commission the salesperson makes
s = amount of sales
The variables in the equation are c and s
The independent variable is s
The dependent variable is c because it's value is determined by the amount of sales of the salesperson
