Given the following reasoning and answer, what was the question? An hour has 60 minutes. If each call lasts an hour, the total amount of money charged is 60 * .05 = $3 for 1 customer. When she talks to 50 clients in a week, the total amount of money charged is 50 * 3 = $150. In a month of 4 weeks, the phone bill is 150 * 4 = $600.
 The answer: 600
