About this document
Average Cost Analysis of Cell Phone Plan by Kairos Noel Daron is a document available to read on EtoBox.
1) A cell phone provider offers a new phone for $600 with a $70 monthly plan. To calculate the average monthly cost, we add the one-time $600 payment to the $70 monthly fee and divide the total cost by the number of months. 2) The total cost function is f(x) = 600 + 70x, where x is the number of months. 3) The average monthly cost decreases with each additional month of use as the one-time $600 fee is distributed over more months. The average monthly cost will be less than $80 after 60 months.
