A customer calls and has questions about the bill for their first month's subscription. They want to know why the monthly rate is $45.00, but the bill is for $60.00. What is the most likely reason for the bill being this amount?
The most likely thing that has happened in this case is that a fee is paid for the registration. The function that best models this problem is: y = 45x + 15 Where, x: number of months. Y: payment of each month. For the first month we have: y = 45 (1) +15 y = 45 + 15 y = 60 answer: the most likely reason for the bill being this amount is registration fee.
