A phone company charges a base rate of $40 a month for service. The user is charged $0.20 a minute for every minute used. The total amount charge to the customer, p, for any number of minutes, m, can be represented by the function
p = .2m + 40.
What is the dependent variable?

• The # of minutes used

• The base rate of $40

• The total amount charged to the customer

• The $0.20 per minute
