graph attached
Step-by-step explanation:
Quentin earns $30/week
w = weeks
s = saved money
s = 30w
s depends on w. Each week he adds $30 to his total amount, so to know how much money he has in the end of each week, we need to multiply 30 by the number of the week.
independent variable = w
dependent variable = s
